Kruskal's algorithm finds a minimum spanning tree in an undirected, connected and weighted graph. We will use a union-find algorithm to do this, and generate a random maze from a grid of points.

In part II of building arc diagrams in D3.js we will build the actual diagram with data from ride hailing app trips we prepared in Part I. Drawing the arc is the most complicated part of this visualization, and we will go through it step by step.

You might be familiar with force layouts in D3.js to create things like bubble charts, network graphs and many other types of visualizations. In this post we will create a force layout bubble chart with multiple clusters along a timeline.

Today I will go over what a force-directed graph is and how to build one in D3.js. This graph is built using data extracted from New York Times articles to show items that are talked about in the articles.
