This interactive scatter plot visualizes the relationship between GDP per capita and CO₂ emissions per capita for countries across multiple regions from 2018 to 2023, with circle size encoding energy consumption per capita. A slider lets viewers step through years, updating the displayed points and filtering data accordingly. The visualization uses D3 v7 with SVG rendering, employing `d3.scaleLinear` for axes, `d3.scaleSqrt` for circle sizing, and `d3.scaleOrdinal` with `d3.schemeTableau10` for regional color encoding. Tooltips appear on hover, and a status bar shows the currently selected country. Data is loaded from a local CSV file.
