This visualization depicts a scatter plot of data points positioned by x and y coordinates, colored by a p_slowness value using a sequential color scale with the `d3.interpolateTurbo` interpolator. The plot includes x and y axes with labels, a color legend, and density contours computed via the `d3.contourDensity` API, rendered as stroked paths using `d3.geoPath`. It is built with the D3 library version 7.9.0, using an SVG rendering approach with a responsive resize observer.
