Summarise categorical features of clusters

For example, what is the composition of industry within each cluster? There are many ways of doing this:

1. Create a matrix of categorical values in a column against each cluster
2. Draw a stacked bar comparing the composition
3. Create a packed circles representation
4. Create a dot chart infographic etc.

Suggestions from Anand for the relevant MR

• Move the distribution into a separate tab. Enable that in data.yaml via a visuals: {mix: true}.

• We can specify columns to group by using visuals: {mix: {columns: [Col1, Col2, Col3]}}.

• Reduce the height of the bands from 100px to 30px

• Move the label "Cluster 0", "Cluster 1", etc above the band.

• Add a colour legend for the categories below the bands. Limit this to the top 10 most frequent categories.

• Render the bands using Canvas, not SVG.
