This interactive line chart visualizes humidity levels in Delhi over time, with the date on the x-axis and humidity percentage on the y-axis. Built with React and D3 v5, it loads CSV data from a GitHub gist and renders an SVG line using `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisLeft`/`d3.axisBottom`. The chart includes labeled axes, a title, and margins, fixing the y-axis domain from zero to the maximum observed humidity value.
