Network Visuals

Network visuals may be used to represent many systems and structures. Our implementation is dynamic, with ongoing optimization adjustments that implement a force layout based on the Barnes–Hut approximation. It also includes many manual setting adjustments.

We are working with dataset NCAA Basketball for years 1985 through 2018. You can download the data from ncaa_basketball_results.csv.

For an overview of shelves that specify this visual, see Shelves for Network Visuals.
