co2_temp_sealevel_scatter
This animated scatter plot visualizes the chain reaction between cumulative CO₂ emissions, temperature anomaly, and sea-level rise. Each circle represents a year, positioned by CO₂ emissions on the x-axis and temperature anomaly on the y-axis, with bubble size and color encoding sea-level rise. A tooltip reveals exact year, CO₂, temperature, and sea-level values on hover. The animation progressively reveals data year by year, with circles transitioning from the origin to their final positions using D3's `transition()` API. The visualization uses `d3.csv` to load the Gist-hosted dataset, and SVG circles with `d3.scaleLinear` and `d3.scaleSequential` for scaling and coloring.
