Overview
Welcome to my Baseball Season Data Analysis page. Here, you’ll find a collection of visualizations and data tables that provide insights into the current MLB season. All of the data come from baseball-reference.com, and the page is updated on a daily basis during the regular season and post season.
Animation of Cumulative Wins, by Team, Over Time
The first visualization is an animation of cumulative wins, by team, over time. This animation allows you to see how each team’s record has evolved throughout the season, and get a sense of which teams are consistently performing well and which are struggling. You can use the controls to pause, rewind, and fast-forward through the animation, and see how each team’s record changes from day to day.
Trend Graphs of Cumulative Wins Over Time
In addition to the animation, I’ve also included trend graphs of cumulative wins over time, arrayed by team. These graphs allow you to see the overall trend in each team’s record over the course of the season, and get a sense of whether a team is on the rise or falling off.
Scatter Plots of Runs Scored vs. Runs Allowed
Another visualization I’ve included is a set of scatter plots of runs scored vs. runs allowed in each game of the season, arrayed by team. These plots allow you to see how each team is performing offensively and defensively, and get a sense of which teams are particularly strong in one area or the other.
Bar Graphs of Games Played by Run Differential
I’ve also included bar graphs that show the number of games played by each team, broken down by run differential.
Bar Graphs of Run Differential Over Time
In addition to the bar graphs of games played by run differential, I’ve also included bar graphs that show the run differential for each team over time. These graphs allow you to see how each team’s performance has evolved over the course of the season, and get a sense of whether a team is consistently strong or prone to fluctuations.
Data Tables with Choropleth Shading
Finally, I’ve included data tables that compare individual players’ batting, pitching, and fielding stats, with choropleth shading to highlight the best and worst performers in each category. These tables allow you to see how each player stacks up against their peers, and get a sense of which players are having the most impact on their team’s performance.
I hope you find these visualizations and data tables helpful in understanding the current MLB season. Thank you for visiting the page.
