Thank you Jane [[user:Jhoffswell]], the VegaJS team, and [[user:Primaler]] who designed the original graph!
P.S. See graph demo page for examples and tutorial links https://www.mediawiki.org/wiki/Extension:Graph/Demo
P.P.S. The "click to open a page" feature is still missing in Graphs extension, but is on my todo list.
