[go-nuts] Re: Graphing libraries in golang
SVGo is library for SVG generation, but others (some cited in this thread), have used it as a basis for building graphics and visualizations. See: [1] for examples (including how to interface to data, there's even a barchart [2] example :) [1] https://speakerdeck.com/ajstarks/the-other-side-of-go-programming-pictures [2] https://github.com/ajstarks/svgo/blob/master/barchart/barchart.go On Friday, September 29, 2017 at 1:42:50 AM UTC-4, Vikram Rawat wrote: > > By graphing I actually meant *data visualization libraries* > > SVGO would be so hard to pass a data to and design even the basic and > simple *BARCHART* > > other ones don't have enough documentation to understand how it works. > > and The reason I am trying GO is that R is slow.
