Goal is to replace react-sparklines in Discord with chrome://webrtc-internals style graphs. timeline_data_series.js and timeline_graph_view.js are taken from https://github.com/fippo/webrtc-externals.
npm install webrtc-internals
Please see https://github.com/vassjozsef/webrtc-internals-test:
const {TimelineDataSeries, TimelineGraphView} = require('webrtc-internals');
const canvas = document.getElementById('canvas')
const graphView = new TimelineGraphView(canvas);
const dataSeries = new TimelineDataSeries();
graphView.addDataSeries(dataSeries);
const timestamp = Date.now();
dataSeries.addPoint(timestamp, Math.random());
graphView.updateEndDate();
