This visualization shows the cumulative growth of TMDb movie counts over time, with a bar chart displaying the running total for each year on the x-axis and the cumulative number of movies on the y-axis. Using React and SVG rendering, the code loads data from a CSV file with d3.dsv, parses years with d3.timeParse, and maps values to positions via d3.scaleTime and d3.scaleLinear. Bars are appended as SVG rectangles with steelblue fills, while d3.axisBottom and d3.axisLeft generate the axes, and axis labels and a title are added as SVG text elements.
