This is not a charting library. No charting library will ever be complete with all the various charts that you could want; if you are using d3.js then you know this already. Instead, this is a framework which handles the boring plumbing - like drawing axes, labels and setting dimensions - leaving you free to do the Hollywood coding.
See the wiki for how to use ninjaPixel.js
After cloning your fork of the ninjaPixel.js repository, from the terminal navigate to the code directory and install ninjaPixel's dependencies by running:
npm install
ninjaPixel is written in TypeScript; the .ts files are located in the code\src directory and the compiled ninjaPixel.js file is output to the code\dir directory. There is a gruntfile configured to compile the TypeScript files and concatenate them into a single JavaScript file. Again, from the code directory run
grunt
This will create ninjaPixel.js and ninjaPixel.bundle.js. The later includes d3.js and the d3-tip extension.
Include your new TypeScript file in the code\src directory (alternatively, if you'd prefer to write in Javascript then save the new file into the code\src\js directory). Modify the concat-basic options in the gruntfile, to include your new file. Once complete, run grunt.
There are some demo pages located in the demo directory. Run the webpages with
npm run demo
