An animated scatterplot visualizes synthetic planetary data, cycling the x-axis among diameter, moon count, and orbital period while plotting moons on the y-axis. Points are colored green with hover tooltips showing name, type, diameter, and moons. Built with D3 v6, it uses `scaleLinear`, `axisBottom`, `axisLeft`, and transition methods to smoothly update positions every 2.5 seconds. Data loads from a CSV file, rendered as SVG circles with a dark theme.
