This bar chart displays earthquake counts across U.S. states for the Western region in 2011, sorting states from highest to lowest frequency. The visualization uses D3 v5’s `scaleBand` for the y-axis, `scaleLinear` for the x-axis, and `axisBottom` for tick marks, rendering as SVG. Data is loaded from a CSV file and filtered for the specific region and year, with bars sized proportionally to earthquake counts.
