Haven't had much time to devote to new visualisations, mostly because work and baby have taken the precedence.
But I just wanted to take a few minutes to share the latest version of the script I showed last time.
It now saves to a pdf file, but that's not the largest change. I actually included one more slice which is obtained from the others with a formula (e.g. average, or geometrical mean, in this case the sum) and is used to rank the pies accordingly. The new value is represented as a white wedge on top of everything else, with its value pasted over it. The script wraps compounds and fit only a limited number per page, then moves on to the next one
There are a lot of things which may be changed, such as having the value as a bubble at the centre rather than a new wedge, to conserve the pies' proportionality... Or just showing the 'score' in a corner of the plot, with other info at the bottom... None of this is implemented as of yet, sorry. The code commented-out shows some graphics alternatives which I did try and set aside for the moment.
