Radial Franchise Networks for all MLB Franchises

All 30 MLB Radial Networks are now complete, and available for you to explore. One thing to notice is that each network will have a slightly different (or radically different) shape, depending on how many (or few) players started in a single season. If the team was in the midst of a successful run, the radians will tend to be short, as fewer rookies or acquired players will debut. On the other hand, teams that are retooling will tend to have long radians, as there are many new players making the team. This could also be reflected in the number of players getting a September call-up from the minors.

While these networks are pretty attractive to view as static images (IMHO), the real fun comes from the interactivity, where you can click, zoom, pan, and see all the details for who played with whom over the course of a franchise’s history. Note that this is based on seasonal rosters, so not all connections actually played together at the same time of the season.

Anyhow, check out a handful of examples, and then try them out yourself at the Franchise Radial Networks 1901-2019 page.

Another Tigers Network Graph

I’m having a lot of fun creating network graphs using Gephi, and excited about the possibilities for displaying a wide range of baseball information. My initial pass at showing team connections uses the Tigers, with this version incorporating all players from 1901 through 2013. Try it out here.

Update – new version with Tigers colors: Updated version

This is done using a radial axis layout with Chinese Whispers Clustering, based on a paper by Chris Biemann. The colors along each of the axes is based on the clusters created by this algorithm. Once again, I’ve used Sigma.js to create the interactive version, so you can dive into the graphic and gain an understanding for how the data is displayed. Here’s a static view of the graph:

Tigers-1901-2013-graph

Kind of colorful, isn’t it? For those of you who are long-time Tiger fans, you’ll soon detect that each cluster (color) represents a specific era in Tiger history, an by clicking on individual nodes, you’ll be able to see which players connect across multiple clusters. Typically, this will be players like Alan Trammell, Ty Cobb, and others who played many years with the club, and thus transcend their own cluster position.

Not sure if this will be the style for all the franchise graphs I plan to do this year, but it feels close, given the ability to display more than 1500 players and nearly 48,000 connections without having things too cluttered.
