Sequences sunburst

Sequences sunburst:

'via Blog this'

I love data visualization. I love AI.

I want to love this visualization (of papers at the CVPR conference), but my wanna love is outweighed by my "I hate data viz that is too low bandwidth".

You can only "understand" this visualization interactively, by flying over the pie chart slices to see the labels. For somebody like me, who tends to absorb a whole picture all at once, this is much slower than presenting the piechart with labels or a legend.  Even if the legend is just color coded, because the labels don't fit.  But if the labels can be spatially attached, by proximity or by arrows, all the better.

I don't really have a photographic memory, but I have a cartoon-ographic spatial memory.  I remember pictures, usually highlighting the important areas. Sometimes my visual memory is augmented by time domain "zooming" into areas of interest.

This flyover graphic requires time domain sequential memory just for the first level absorption.  At the very least it is slower; but I suspect it also displaces the use of time domain memory for deeper understanding.

I am impelled to blog this because it is so bloody easy to make this visualization higher bandwidth.

It's a nested pie chart.  There is room for the labels for most slices of the innermost pie ring.  Even on the outermost pie ring.   I.e. without even changing the graphic most of the segments could be labelled, with interaction to dive into the segments too small for such trivial labelling.

And if you have the ability to explode sections - dynamically redraw - even more so.

I have probably made an enemy here, if this ever gets back to the author. (If you are the author, I would love talk to you.  If only to thank you for the raw data wrapped in this visualization.)

I have probably also dated myself, because video presentations are more and more the fashion.

Yes: I am the sort of person who hates watching videos, because I can read papers or slidesets faster than videos.   When I watch videos, I like fastplay and fast forward. I especially like video players that  recognize slide boundaries, so that I  can jump from slide to slide - and then only backtrack when it seems likely to have interesting discussion.

  • We can talk faster than we can type
  • But we can read faster than we can listen. Or watch video.

So, which is more important?
