This line chart visualizes average anime ratings from 1963 to 2022, with the year on the x-axis and the average rating on the y-axis. Using D3 v5, the chart scales time and linear data with `d3.scaleTime` and `d3.scaleLinear`, and renders axes with `d3.axisBottom` and `d3.axisLeft`. A green, three-pixel-wide line is drawn with `d3.line` and `curveBasis`. The data is fetched via `d3.csv` from a GitHub Gist, and the SVG output includes custom labels and a title.
