Graphv

Overview

Port of the NanoVG C library to (mostly) pure OCaml. This library is still a work in progress, the documentation is not complete and there could be more examples. Some context flags are also not passed down to the backend renderer yet.

Docs

Docs can be found here. They are still a work in progress.

Screenshots

Demo

A live web demo can be found here. If the fonts look wrong the first time, refresh.

Performance varies quite a lot between browsers, Chrome tends to be the fastest. The demo supports mouse and touch events. Clicking/tapping will zoom the top-left widget, hovering the text will highlight rows, and two fingers on mobile will allow zooming/panning. Dragging a single finger on mobile will make the eyes follow the finger.

Performance

Below is a table of eye-ball measurements of frame times across platforms compared with the native C implementation of NanoVG. All times are in millseconds (ms). Measurements were taken on a MacBook Pro Late 2013 laptop. The program being tested is the one shown in the screenshots above.
