Our end goal was to create a visualization of a network that a user could click on that would do the following things: display immediate subgraph of a selected node, display shortest path between two selected nodes, and display most likely path between two selected nodes. We decided the best approach would be to start with a small test network, and set up a graphical system that would visualize the network and allow for user interactivity.

The test network featuring my boss’s daily movements was a .CSV and is shown below:

The origin and dest columns represent the nodes (places my boss goes) connected by…
