This example visualizes the Titanic passenger manifest, mapping each first-class passenger’s fare and age group. It uses `d3.forceSimulation` to position circles by passenger attributes, with color encoding survival status and gender. The code performs data loading via `d3.csv` and filters the dataset before rendering with SVG circles. It highlights fare disparities and demographic clusters among survivors and non-survivors, drawing directly from the provided `titanic20180616_coma.csv` file.
