This line chart visualizes the number of comments over time from a CSV dataset. The x-axis represents time, while the y-axis maps temperature, though the data lacks a temperature column. Built with D3 v5, the code uses `select`, `csv`, `line`, `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to render an SVG with grid lines, axis labels, and a smooth curve. The chart displays a title and styled paths via CSS.
