This example presents a line chart of India’s average annual temperature from 2000 to 2023, drawn in SVG using D3 v7. The visualization plots a teal monotone curve with orange circular markers for each year’s temperature value. It uses d3.csv to load climate data from a GitHub gist, d3.scaleLinear for the x and y axes, and d3.axisLeft and d3.axisBottom to render ticks with gridlines. The chart includes labeled axes and a title, with data filtered to a single country and sorted by year.
