This scatter plot visualizes the relationship between age and weight in kilograms, with each point colored by workout type from the lifestyle.csv dataset. The visualization uses D3.js v7 with SVG rendering, implementing linear scales for both axes, an ordinal color scale with the Tableau10 scheme, and gridlines for readability. Interactive tooltips appear on hover, while axes are labeled and accompanied by a legend. The code includes a fallback dataset if the CSV file fails to load, and it cleans the data by filtering out non-numeric values.
