Consider examples on creating graphs: https://sites.google.com/view/cps-iot-sibsust-2019/graph
Make 9 new files, like graph01.html, graph02.html on the disc and examine functionality of the examples; to open it with browser we should enter address in Chrome: file:///home/.../graph01.html) The last example provides the class for graph. In addition to the graph that is already created, add two additional graphs (create two new objects):
graph2 = new Graph("canvas2", 200, 1000);
graph3 = new Graph("canvas3", 200, 1000);
The result should be three graphs as seen in the following figure; we create the file on disc (e.g. assignment05.html) and open it with browser (in Chrome address we enter: file:///home/.../assignment05.html):
