This visualization plots earthquakes from the 2019 Ridgecrest sequence, with time on the x-axis, magnitude on the y-axis, and point size encoding depth. The interactive scatterplot uses the vega-lite-api to construct a layered specification, registering with vega-lite and vega for rendering. Tooltips display exact earthquake magnitude and depth values. Data is loaded as CSV via d3.csv from a GitHub gist, and the chart fills the browser window with a custom config for darker labels and grid-free axes.
