Line Chart Race vs Bar Chart Race

A line chart race (also called a horserace chart or bump chart) shows the same time-series data as a bar chart race but emphasizes trends and trajectories rather than rankings. Lines crossing each other make overtake moments dramatic, while the cumulative path reveals long-term patterns that single-frame bar charts cannot show.
