How I Made That: Animated Square Pie Chart
Also known as waffle charts. Using animated transitions between values, you can allow for comparisons between categories.
I’m a fan of element-based visualization methods, because they tend to shorten the path from abstract data back to reality. So when I wanted to compare percentages across various demographics, I went with the square pie chart instead of stacked bars or standard pie charts.
I’ve made these in R, but this was the first time I made them using d3.js. I wanted animated transitions when you switched between different groups of people. Here’s how I made it.

How to Make Stacked Area Charts in R
From the basic area chart, to the stacked version, to the streamgraph, the geometry is similar. Once you know how to do one, you can do them all.
Moving Past Default R Charts
Customizing your charts doesn’t have to be a time-intensive process. With just a teeny bit more effort, you can get something that fits your needs.
Build Interactive Area Charts with Filters
When you have several time series over many categories, it can be useful to show them separately rather than put it all in one graph. This is one way to do it interactively with categorical filters.
