Explore the Press On JavaScript framework

This web page provides a convenient way to try out and experiment with the JavaScript code from the book Press On. It provides a range of pre-defined devices you can experiment with, a JSON import so you can define your own devices, and an export function (currently supporting JSON, GraphML, SCXML, Dot and Mathematica data formats).

Please pick from the devices available:

1. Enter your own JSON model
   • Note that you can use any of the other devices (listed below) to get an initial JSON model to edit to experiment with: choose a device to explore, then choose 'JSON Model' to get its JSON code.
   Paste your own JSON model below, or copy-and-paste a pre-defined JSON device.
   You can click to get a device from the list below, and then edit it at will.
