To learn more about a language I rewrite some of the core functions, or compare basic speeds of each set of functions per problem to see what is more suited in real world situations.
Other than an ugly online line-graph generator which often only allows one or two series, I cannot find anything that would suit what I need.
Do you know of any online service, or better a easy to use framework/graph software I could feed data in for my benchmark results? It can be more complex (I might look into graphvis if it is suitable), but other benchmarks on for example OS's have clean formats, using a script I just cannot find that renders it.
