Weekly Data Viz Decomp: Global Sea Ice Level

Weekly data visualization decomps to keep a look out for technique and learning: Global Sea Ice Level I found on Reddit’s DataIsBeautiful 

Decomposition of a Visualization:

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • Months on a radial axis
      • Sea level area scale on radial area
      • Lines along radial to represent sea ice level
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Quantitative, Continuous
    • Encodings (Shape, Color, Position, etc.):
      • Color hue and position for line
  • What works well here?
    • The animation and showing the change through time is particularly effected as the overall area shrinks
    • The color hue change to a lighter color for current years is particularly effective
  • What does not work well and what would I improve?
    • The colors seem to be a little off theme – maybe personal nitpick but I would have picked a blue hue or something that relates to the water more
    • No sure how much the seasons adds to this chart, but I like the use of the area on this chart rather than one with a simple xy-axis
    • Maybe add an interactive filter for years to see contrast
  • What is the data source?  Do I see any problems with how it’s cited/used?
    • Cites what looks like a scientific journal – would have liked a link or publication, but I’m not familiar with this subject area
  • Any other comments about what I learned?
    • Makes me want to use a radial chart for something when I get a use case for it

Why I Can’t Find Recycling Bins in NYC (visualized)

Although I love NYC, as a Californian transplant the one big pet peeve I have other than the lack of Mexican options and fresh avocados is the lack of recycling and general awareness of doing so. Yes, I’m that Californian who brings the reusable bags to the market and carries a water bottle at times in NYC.

I couldn’t help noticing walking around how many people buy items like bottled water and have no place to recycle them even though NYC has a lot more public waste baskets than a lot of other cities. Taipei, I’m looking at you and all those days I carried my trash for miles.

I played with some of the NYC Open Data in Tableau and did confirm how few Public Recycling Bins are in NYC.

For some reason they’re particularly absent in Queens, outer Brooklyn, and Upper East Side. Population density seems to have no impact. Shrug, come on NYC, you “progressive bastion,” get your recycling on! It kills me seeing how many people here buy beverages in containers that could easily be recycled and toss them into a regular trash bin. It’s crazy.

Weekly Data Viz Decomp: Visualizing the Burden of Cancer

Weekly data visualization decomps to keep a look out for technique and learning.

This week’s decomp of Visualizing the Burden of Cancer: Incidence Rate by 32 Cancers from 2005 to 2015

Decomposition of a Visualization:

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • How number of occurrences of cancers have shifted between 2005 and 2015 – date encoded with huge and increase and decrease done with green or red
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Quantitative, continuous
    • Encodings (Shape, Color, Position, etc.):
      • Position, Color Hue
  • What works well here?
    • Showing large changes
    • Filtering functions
  • What does not work well and what would I improve?
    • Small changes looked too scrunched
    • Weird that increase and decreases are show on same axis, would have changed it to show decreases on a double axis
  • What is the data source?  Do I see any problems with how it’s cited/used?
    • No, great full academic citing here
  • Any other comments about what I learned?
    • Always difficult to use this type of chart with data of varying ranges – not sure I would have done that much better

Weekly Data Viz Decomp: The Guardian’s Premier League Transfer Window Summer 2016

Weekly data visualization decomps to keep a look out for technique and learning.

This week’s viz: Premier League: transfer window summer 2016 – interactive

Decomposition of a Visualization:

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • Bubble size for size of transfer
      • Color hue denoting transfer or out of team
      • Position for date close to transfer window
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Qualitative and categorial
    • Encodings (Shape, Color, Position, etc.):
      • Shape, position, size, color hue
  • What works well here?
    • Showing a small multiples type view for each team and their transfers
  • What does not work well and what would I improve?
    • Having the totals summary numbers on the side of the charts is a little unorthodox and unintuitive
    • Bubbles seem to be placed arbitrarily without thought to the y-axis, even though the x-axis has meaning
    • Not immediately clear why some players are featured and noted in tooltips versus those that are not
  • What is the data source?  Do I see any problems with how it’s cited/used
    • Seems to be original Guardian data collected about the English Premier League, but not as clearly stated as I’d like to expect
  • Any other comments about what I learned?
    • Example of something pleasing to the eye in terms of color hue and perhaps some flash factor, but perhaps not that functional to explore upon closer examination.
      • Certainly sense for the purposes of the Guardian though in putting out this story and is a technique I’d borrow if I had a use case
      • Good for showing a bigger picture view
    • Probably not worth it in terms of the work it would be taken incrementally as filters are difficult to work and can be computationally expensive, but the nerd in me would have liked to search for the player

Weekly Data Viz Decomp: Your City’s Kickstarter Scene Visualized

Starting off with these weekly to keep a look out for technique and learning.

This week’s viz: Your City’s Kickstarter Scene Visualized

Decomposition of a Visualization:

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • Cities and founding for Kickstarter projected, shown in packed bubbles
      • Barchart breakout breakout with heat using color hue categorized in a data table
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Quantitative
    • Encodings (Shape, Color, Position, etc.):
      • Shape, position, size, color hue
  • What works well here?
    • Showing size of funding relative to each other in a large scope, used with the size of the bubbles for individual projects in each city and the packed bubble sizes comparing city to city
  • What does not work well and what would I improve?
    • Would want to be able to filter more, by number of backers for instance to improve explorability and hide the bubbles
  • What is the data source?  Do I see any problems with how it’s cited/used?
    • Kickstarter data, straight from the source
  • Any other comments about what I learned?
    • Good example of a lot of data put into one place to be compared with relative ease
    • The analysis the goes with it is critical because most viewers will not spend enough time to do the analysis themselves to glean the ton of insight here

 

More MLS 2015 Visual Exploration Tools

Previously, I created an interactive view just looking at goal breakdowns by Major League Soccer teams overall for the 2015 season.  I’ve added several more frames to look at the breakdown of the same dataset to this new view in a exploratory way to see variables that correspond or not.

MOTIVATION

As per verbatim from my previous post:

I’ve really into soccer in general, especially international play, after my grad school project where I worked at the Annenberg Innovation Lab collaborating with Havas Sports and Entertainment and IBM on a research project studying soccer fans (see Fans.Passions.Brands, Fan Favorites, and Sports Fan Engagement Dashboard). I also did my degree practicum on Marketing to Female Sports Fans.

I’m now in another universe creating data visualization at an advertising agency and am trying to combine the geeky fandom with practical practice related to my daily work.

 

DESIGN

I deliberately tried to use Tableau components and styling that was out of the ordinary, to some mixed level of success.  I put in a custom color palette in the Tableau repository preferences file.  Also, I tried to take advantage of using the context filters (when you click on one bar graph of a team for example, the other charts only show stats about that team you just click on instantly), scale filters, and pivoting the data on the third dimension, using both a color gradient and size of a value in a chart for instance.

TECH

Trying to stretch the design and exploratory strengths of Tableau here.  The one knock I give for Tableau in 2016 is that it doesn’t present data in a sexy enough way compared to Javascript-based visuals.  On the other hand, none of the Javascript based tools democratizes creating views you can explore with some pretty heavy statistical tools, one could some of the basic functions many people use SPSS for could be better left using Tableau as one integrated tool.  In particular, I utilized the r-squared and p-values to show correlations across different metrics that might matter or be interesting to see how they hold to some teams or not.  There’s not much of correlation between Corner Kicks and Goals for teams overall for instance, but there is greater negative correlation for those teams who have more losses.

Esc the City Un-Conference Talk: Simple Slide Design and Data Viz Crash Course

I’m currently attending a program called Escape the City which “helps mainstream professionals make proactive & entrepreneurial career changes.”  We’re part of the “Founding Members” cohort as the first iteration of this program stateside.

I’m not looking to leave my current job, which I’m pretty happy with. I definitely did want to meet other ambitious people and unconventional thinkers.  A mentor who had done the program in London, where Escape started, said I’d benefit.  I have been loving it so far.  I’ve found it beneficial to being more present, proactive, and creative at work and outside of it.

One of part of the program we did last night was the Un-Conference, where individuals in the program presented on different topics: everything from Learnings from Training for Endurance Races, Self-Acceptance and How to Love Yourself, Web Development 101, Relaxation with Origami, to name just a few.

As part of building on my knowledge and sharing it, I did a talk on Simple Design with a Data Visualization Crash Course below.  I hope my fellow participants found it useful, especially since many of them are thinking about starting and pitching their own businesses.
