Announcing rt-graph, a real-time graphing tool

A real-time graphing experiment written in Rust.

Many other graphing tools do not efficiently update the display when new data is added, for example redrawing the whole screen when only a few pixels of new data are added.

This crate tries to do the minimum incremental work required to update the graph when new data is added: draw the few pixels of new data, and scroll the graph with efficient large copies, which can and should be accelerated by GPU hardware.

As a result of this design rt-graph easily copes with 30k new points per second, at 60 FPS, using just 3% CPU (tested on a Lenovo T460 laptop from 2016 with 2.4 GHz Intel Core i5-6300U, running Ubuntu 18.04.5).
