What is a Bump Chart?
A bump chart is a type of data visualization that shows how the rankings of different categories or entities change over time. Unlike a traditional line chart, where the y-axis represents a quantitative value, the bump chart’s y-axis shows rankings (for example, 1st, 2nd, 3rd, etc.), and the x-axis represents time or another ordering variable.
Each line in the chart represents a single category or item, and the way the lines move - rising, falling, or crossing over one another - makes it easy to spot how rankings shift at each time point. When lines cross, it signals that the relative ranking between two categories/entities has changed.
