This scatter plot visualizes the relationship between age and insurance charges using data loaded from a CSV file. D3.js v7 scales map age and charge values to SVG circle positions, with axes labeled and a title displayed. The visualization uses d3.csv to fetch external data, d3.scaleLinear for both x and y domains, and d3.axisBottom and d3.axisLeft to render the axes. The SVG rendering approach draws each data point as a small blue circle.
