This scatter plot visualizes happiness scores against levels of social support for countries worldwide, using data from the UCI Machine Learning Repository’s Auto MPG dataset loaded via D3’s `csv` method. Each circle represents a country, positioned by its happiness score (x-axis) and social support index (y-axis), with axes generated using `axisBottom` and `axisLeft`. The SVG rendering includes gridlines, axis labels, and a title, while circles use a semi-transparent purple fill. The implementation leverages `scaleLinear`, `extent`, and `scaleLinear` for scaling, and appends circles to the SVG via `select` and `data` joins.
