A lightweight library to model graphs, run graphs algorithms, and display them on screen.
You can use this library to create arbitrarily complex graphs and run algorithms and transformations on them, or just use it for visualization, importing graphs or even embeddings created in other languages/platforms and serialized using JSON.
Graphs can be embedded in the plane, vertices can be positioned arbitrarily, and both vertices and edges can be styled individually.
From the base folder:
nvm install stablenpm install
From the base folder:
npm t test/$FOLDER/$TEST
npm t test/geometric/test_point.js
To bundle the library, I used Webpack - but you can use whatever you like.
npm run bundle
A word of caution, though: the combination of ECMAScript modules and advanced features (ES2019) makes configuration non-trivial.
Check out how to configure babel plugins in webpack.config.js.
For an introduction to Graph, feel free to take a look at "Algorithms and Data Structures in Action In particular you can check out online, on Manning's livebook site:
- Chapter 14 for an intro to graph data structure.
- Appendix B for an intro to Big-O notation.
- Appendix C for a summary of core data structures like trees or linked lists.
To learn by example what you can do with JsGraphs and how to do it, check out this tutorial.
