On behalf of a customer, I'd like to request for Mekko charts.
A Mekko Chart shows the relative importance of items by both height and width. See the following example:
Here you can directly see:
- Three different products
- Horizontal: the cost
- Vertical: the nr of items per product
- Area: Total cost per product.
Perhaps it can be incorporated in the work on Highcharts? See https://www.highcharts.com/demo/variwide
