This visualization presents a scatter plot that examines the relationship between a passenger's age and ticket price. The plot uses D3.js v6 to render the data as individual circles on an SVG canvas, with axes labeled and scaled according to the data's extent. The data is loaded remotely from a GitHub gist and parsed as CSV, with values converted to numeric types for accurate plotting. The code uses D3 API methods including `d3.scaleLinear`, `d3.extent`, and `d3.axisBottom`/`d3.axisLeft` for the coordinate system.
