Makeover Monday - marimekko with step

My entry for Makeover Monday week 14, which was based on the data from a Guardian article and PwC report on the affects of automation on UK jobs.

The chart is vertical marimekko chart, just using rects and manually calculating the offset of each row, rather than using the d3 treemap function, like this example.

Built with blockbuilder.org, layitout.com, and Bootstrap.
