A computer drawn higraph. A number of rectangular sets are connected by smoothly curving edges.

A #Higraph milestone: Blobs (nodes as sets) now work! Grab a 'parent' blob, and all the children move. Edges connect anywhere on the blob, and default to be orthogonal to the point of contact. graphML read and write working.

Now on to proper hyperedges!

A nested set of round-cornered rectangles. Very similar to a Venn diagram

Hi #Mathstodon - a #GraphTheory question:
Given the following visual set containment, I can obtain the total containment of every item as a list (text on the left). This intuitively seems sufficient information to derive the containment graph (almost a tree - […]

@MrBerard #Higraph editor question:
So far, it has been possible to round trip models from my tool into yEd and back. I'm now developing more higraph specific functionality that they don't explicitly support. But the graphML spec has a very _similar_ idea (nested graphs). Is it worth the effort […]

If I did everything right, I have a public alpha release of my graph (nodes and edges) editor
With source and windows binary !
(I hope)
It's a rolling chassis, to explore the design patterns for the ultimate goal of a #higraph editor.

A screenshot of a Windows 98 (virtual) computer running a vector graphics tool. Rounded rectangles are joined by some curving, arrowed lines.

I was looking for an icon for the Version 00 release of my #Higraph tool, and remembered that my 1999 version had one.
I had to fire up a #WIndows98 VM, and access the files via IE5 and XAMPP on my PC, but here it is. Zipfile with full system is there for […]
