This bar chart displays monthly values over time, with each bar’s height representing a numeric amount in dollars. The chart uses D3.js (version 3.5.17) to parse date strings from a CSV file, map dates to ordinal positions on the x-axis, and scale values linearly on the y-axis. Axes are rendered using `d3.svg.axis` with rotated tick labels, and the bars are drawn as SVG rectangles filled in steel blue.
