This bar chart displays the average runs scored by cricket players, grouped by their country of origin. Built with D3 v7, the visualization aggregates data from a CSV file using `d3.rollups` and `d3.mean` to compute country-level averages. The SVG rendering uses `d3.scaleBand` for the categorical x-axis and a sequential color scale to encode the average runs value, with interactive tooltips appearing on mouseover.
