Issue with large family

[Timothep]

Hi, I'm getting this error when working with a large family:

kingraph genealogy.yml > genealogy.svg

Error:

I raised the Memory for viz.js as suggested by @momack2 in this other issue but it doesn't seem to help.

It seems to have to do with the family size among one house. This error occurs when it has more than 24 parent/children pairs.

Any idea what is going awry there?

When I edit the vis.js file and use Notepad++ find and replace all function to replace 16777216 with 1677721600 I am able to generate large trees, 150+ node trees in my case.

Have you managed to fix this problem?

Iirc, there was some lower level environment variable I was able to increase that unblocked this - but unfortunately I don’t remember where exactly it was. If I remember correctly, dividing a family up into “houses” also helped mitigate some size issues.

I think this issue IS a duplicate of #6, and the simplest solution (to me) seems to me not to bother about tweaking vis.js memory settings, but simply to generate only the dot file with kingraph, and let Graphwiz produce the SVG and PDF. I have recommended this in the README of my fork.
