Donut charts in Graphviz about dtreeviz HOT 5 CLOSED

Does d3 imply it only renders in a browser? Can this donut thing work purely in mpl and graphviz?

Hmm...well,I don't hate the pie charts enough to really worry about this, particularly if it requires that I do some thinking or has anything requiring a browser. ;) if it's okay with you I'm going to close this for now

No worries, entirely your call. No browser required, but, yes, some thinking 😉.

I chose donuts for two reasons:

• In some circles 🙄, nothing says "20th century" quite like a pie chart. Donuts, apparently, are the dessert chart du jour.
• I wanted to overlay a label—a computer transaction ID—on each chart. I preferred the cleaner look of the label on the graph background color rather than on a multicolored pie.

My viz is rendered entirely in Graphviz. I investigated using a different library to render each node in the chart, as you've done, but I hit a roadblock: I couldn't capture mouse events for objects in such nodes. I think that's because Graphviz renders them using the SVG <image> element. This is important to me, because I want interactivity. At some point, I'll revisit that issue, and perhaps integrate the SVG for each node into the main Graphviz-generated SVG—as I've read you've done—rather than referring to it via the <image> element.

Here's an example of what I'm doing:

Essentially, I'm overlaying computer transaction performance data on transaction call structures. Each node (donut) represents a computer transaction. Each edge (arrow) represents a transaction calling another transaction. The size of each node represents the transaction CPU time relative to other transactions: so, the donuts are also "bubbles". I've deliberately omitted the legend because this viz is currently an inhouse project; I don't want to publicize the domain-specific details.

very impressive!
