This example shows the average delivery time by shipping method (Air, Sea, Ground) as a simple bar chart rendered in SVG. The chart uses d3.scaleBand and d3.scaleLinear to map shipping methods and delivery times to positions, with d3.axisBottom and d3.axisLeft providing the axes. Bars are colored steelblue and turn darkorange on hover via CSS. The data is hardcoded in the script, and the chart includes labeled axes for context.
