This bar chart visualizes the distribution of disease types by number of infections in 1968, using a logarithmic y-scale to accommodate wide value ranges. Built with D3 v6, it renders SVG rectangles with maroon fills that transition to crimson on hover, supported by an interactive tooltip displaying exact infection counts. The chart includes labeled axes, a title, and data simplified from the CORGIS health dataset, demonstrating the use of d3.scaleBand, d3.scaleLog, d3.axisBottom, and d3.axisLeft.
