This interactive SVG chart visualizes three climate indicators—CO2 levels, temperature anomaly, and sea-level rise—over time from a remote CSV dataset. The chart uses a linear time axis on the x-axis and a single shared y-axis for all three metrics. Built with D3.js, the code loads the data via `d3.csv`, processes the parsed values, and renders axes using `scaleLinear`, `axisBottom`, and `axisLeft`. The visualization employs a common vertical scale to accommodate the differing ranges of the three variables, with axes and ticks formatted appropriately.
