Ogma does not come with tons of layout algorithms or parametrizations but the handful of layout algorithms will allow you to visualize tens of thousands of nodes while remaining interactive and fluid. Like everything else in Ogma, this comes free of charge. No need to rewrite anything in function of WebGL or change of templates, it just happens.
The layout algorithms work harmoniously with grouping, clustering and styling mechanisms. Like everything else, things are straightforward and effective towards data discovery and business visualizations.
Layout of tens of thousands of nodes while remaining interactive and fluid.
If you have sophisticated graph layout needs, consider yFiles instead. It offers a deep tuning of algorithms. On the other hand, if your app needs a bit of editing and a bit of layout consider looking at Go.JS.
