This example demonstrates a reusable scatter plot that visualizes the relationship between CO₂ emissions and GDP for six countries using data from a local CSV file. It employs D3 v7 with SVG rendering, implementing a `scatterPlot` function that accepts container, data, and variable parameters for reusability. The visualization uses `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to create proportional scales and axes, with circles positioned via `attr` bindings. The code also clears previous SVG elements before re-rendering, ensuring clean updates without duplication.
