This visualization shows the number of applications over time as a purple filled area chart, with the title "Number of Applications" displayed above the plot. The code loads CSV data from a GitHub gist, parses dates with `d3.timeParse`, and renders the chart using D3 v6’s `scaleTime`, `scaleLinear`, `area`, and `curveBasis` APIs. Axes are drawn with `axisBottom` and `axisLeft`, including grid lines and custom tick formatting. The SVG output includes styled axis labels, ticks, and a title, all laid out within specified margins.
