This qualitative scatter plot displays the relationship between passenger age, fare paid, and survival status for 887 Titanic passengers. Each circle represents a passenger, with blue and red indicating survival (1) or non-survival (0), using a color scale from D3’s ordinal scale. The visualization uses D3 v7 to load CSV data from a remote source and render SVG circles, axes, and a legend. The code specifically employs `d3.csv`, `d3.scaleLinear` for the x (age) and y (fare) axes, and `d3.legendColor` to create the categorical legend, with the chart positioned within an SVG container using custom margins.
