This scatter plot visualizes the relationship between an individual's age and the calories they burn, with each point colored according to the workout type from the lifestyle.csv dataset. The D3.js v7 code loads the CSV data and uses `d3.autoType` for parsing, then employs `d3.scaleLinear` for the x and y axes and `d3.scaleOrdinal` with `d3.schemeSet2` for categorical color encoding. The SVG rendering includes axis labels, a title, tooltips on each point, and a legend positioned within the chart.
