This barplot visualizes the running total of a data metric from 1884 to 2010, with the y-axis representing cumulative counts and the x-axis showing years. It uses D3.js v3 APIs such as `d3.scaleBand`, `d3.scaleLinear`, `d3.dsv`, and `d3.axisBottom`/`d3.axisLeft` to load and render data from a CSV file into SVG rectangles. The chart highlights growth trends over time, showing accelerating increases in later decades.
