This scatter plot visualizes the relationship between happiness scores and GDP per capita across multiple continents, with each circle colored according to its continent category. It shows how countries with higher GDP per capita tend to report higher happiness scores, while also revealing regional clusters and outliers. The visualization is built with D3 v7 and rendered as SVG, using a linear scale for both axes and an ordinal color scale for continental groupings. A d3-legend legend provides a color key for the continent categories, and the data is loaded from an external CSV file containing happiness and GDP metrics.
