This example uses an area graph to show the number of runs scored by Virat Kohli in the Indian Premier League across multiple years. It layers a circle mark, area mark, and interactive text and rule marks, with a single selection tied to the x-axis that highlights data points on mouseover. The visualization is built with Vega-Lite API and d3.v5, pulling CSV data from a GitHub gist, and uses custom configuration for axis styling and tooltip formatting.
