How I Made That

Process the data into a usable format, which makes the visualization part more straightforward.

A combination of a bivariate area chart, animation, and a population pyramid, with a sprinkling of detail and annotation.

Mapping one dot per person, it’s all about putting the pieces together.

Also known as waffle charts. Using animated transitions between values, you can allow for comparisons between categories.

Add interaction so that you can show different segments of the data and allow comparisons.

The histogram is my favorite chart type, but it’s unintuitive for many. So I’ve been using the less accurate but less abstract beeswarm.

When there are too many options or categories, it can be helpful to make the data searchable.
