Comet and shadow visualisations

Hi,

I've been using the two chart types shown here:
GitHub - turukawa/whiqicharts: A set of data visualisations for presenting complex time-series data in useful ways. for a few years and finally got
round to sharing them.

I'm interested in presenting multiple, and multiple-dimension, time-series
data in ways that are easy to see, repeatable and printable. The comet
charts, for example, are a static version of Hans Rosling's Gapminder moving
bubble charts.

This is my first ever attempt at Github / open source release so would
appreciate the feedback. Originally these were embedded in Django views
hence any fruity use of the Artist.

Regards

Gavin
