Fork of d3 bar sequential
This bar chart shows the distribution of disease types in 1968, using a sequential color scale to encode the number of infections from light to dark orange. The chart displays each disease category as a separate bar, with the color intensity reflecting the infection count. Built with D3 v6, the visualization uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.scaleSequential` with the ColorBrewer OrRd scheme to map values to colors. A legend, created with the d3-legend library, accompanies the chart, and the data is loaded from a CSV file. The SVG rendering includes labeled axes for disease type and infection numbers, with the chart styled on a black background.
