Categorical data as d3 nodes
Recently, I’ve been messing around with different ways to display categorical data. I do a fair bit of work with categorical data, and in my presentations and reports I was getting a bit sick of bar charts and tables (and pie charts are out).
A nice solution is the use of d3 nodes to map categorical data, like so. Here, each node represents a different user, and by clicking the user buttons at the top you can group them by ‘Group’, or ‘Gender’. (Note that all the data is simulated).
This graphic takes a little bit of coding and customisation, so probably not something you could incorporate into every presentation, but it’s still a nice way of visualising and grouping categorical data. If nothing else it’s a bit more interesting than a bar chart!
