This interactive bar chart displays the cost of accidents across the top 50 major states, using data loaded from a CSV file. The visualization employs React with D3 v5, utilizing `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. SVG rectangles represent each state’s cost, with gridlines and tick labels generated through D3’s axis utilities. The chart presents data in a sorted horizontal layout, rendering directly to the DOM via React components.
