@krinkle Are the different curve directions (some go like e^(-x), others like 1-e^(-x))) artifacts of how the versions are sorted in the legend?

RE: browserstats 

@danielhglus Yeah, exactly. You can play with different sorts at the Grafana link.

I found this the least-worst rendering with minimal effort (where minimal is still an hour or so in total).

If I recall correctly, sorting by version name, means you get either indistinguishable colours (majority new versions at the tail end), or a confusing shape.

For some, this effect was particularly bad and for those I tried to make it better by subtly muting lots of smaller versions.
