I’m doing some form of data visualization learning for 180 days because I need to #JFDI.
*Took day off for Thanksgiving
Data Viz Created:
EXERCISE: Using a data set of your choice, create either a stacked bar chart or stacked area chart. (I recommend a bar chart for categorical data, and an area chart for time series.) Include axes, plus a headline and some brief explanatory text to provide context. Post the bl.ocks.org link to your working page in the forums.
-Working on Stacked Area Chart with LA 311 Data. In progress.
Reading and Learning Data Visualization Theoretically/Critically:
- Did Module 2 Discussion Question
- The primary critique of stacked charts is that an inconsistent baseline makes meaningful comparisons across categories perceptually difficult. So when would you want to use a stacked chart, despite this potential challenge? Post an example to a stacked chart and explain why you find it either appropriate and successful or problematic.
- Stacked charts are good for comparing individual elements across categories in groups. An example is sales data for different products across regions for an at-a-glance look. However, it’s my personal belief they stacked charts should be used carefully and sparingly.How Katrina Washed Away New Orleans Black Middle Class has a good use of a stacked area chart showing demographics. I find the use successful since the time series has a clear point of inflection and that there are only four different measures (in this case ethnic groups) to compare that are clearly delineated so trends are clear.
