Re: [graphviz-interest] Out of memory issue

Hi Greg,

the reason for hanging neato layout engine is 'splines="curved"'.
After commenting out that line (and correcting "layoutEngine" to  
"layout") everything works fine.

6 URL shortener failed badly to shorten 104KB URL, but "manually" this  
is no problem at all!
Here you can see/play with the modified graph:
https://stamm-wilbrandt.de/en/104KB.URL.redirect …

"1000,1000" size is really big, you have to scroll a lot to see something.

Since this online tool is based on Viz.js and that does not allow for  
images there are a lot of errors logged in browser JavaScript console.  
But the layout is done without issues besides that.

Hermann.
