This example shows a line chart of total United States honey production aggregated by year from 1998 to 2012, using the d3.csv, d3.group, and d3.scaleTime APIs to aggregate raw state-level data into yearly totals. The chart renders as an SVG with d3.line for the path and circles for data points, while a custom menu component built with d3.dispatch lets the user select a different quantitative column—such as number of colonies or price per pound—to update the y-axis and line via d3.scaleLinear and d3.axisLeft.
