Description

We are looking for a programmer who would expand the litegraph library (https://github.com/jagenjo/litegraph.js) with additional functions. The litegraph library is a node editor that allows you to create flowcharts and export them to JSON. From the user's point of view, the web application is to allow for the creation of a block diagram, e.g. for temperature monitoring. On the diagram, the user will place the receiving and presentation blocks, after pressing PLAY the temperature will be read via the websocket and presented in the web application.
