D3.js is pretty fun and allows you to build great visualizations with data and JavaScript. The technical storage or access that is used exclusively for statistical purposes. Lets make a call to the GraphObject.makemethod: Now, well add a reference to the GraphObject.makemethod in the $ symbol to improve code readability. I will be using a slightly older version (v3) because I readily created many of my scripts using this version. Importantly, interactive charts can help to not just tell the reader something but let the reader see, engage, and ask questions. There are many D3 examples online but I have not seen such a big list published anywhere so I am dropping it below, with thumbnail images of each D3 demo on link mouseover.
