SVG:::Graph is a pure Ruby library for generating charts, which are a type of graph where the values of one axis are not scalar. SVG::Graph has a verry similar API to the Perl library SVG::TT::Graph, and the resulting charts also look the same. This isn't surprising, because SVG::Graph started as a loose port of SVG::TT::Graph, although the internal code no longer resembles the Perl original at all.
No, it is not. But this github support the svg-graph gem on rubygems. So, is the de facto repository.
I didn't receive any complain from Germane Software, anyway.
The link on the home page is dead.
