This example demonstrates a reusable scatter plot that visualizes Titanic passenger data, comparing age against fare and coloring points by gender. The visualization alternates between two halves of the dataset every five seconds, using a custom `scatterPlot` function built with D3 v6. The chart employs `scaleLinear` for axes, `scaleOrdinal` with `schemeCategory10` for colors, and `axisLeft`/`axisBottom` for tick marks. Data is loaded via `d3.csv` from a remote source, and the animation uses `setInterval` to switch plots, removing and redrawing SVG circles.
