This visualization plots daily closing prices from a CSV of South African index data using a scatterplot of semi-transparent points. The chart is built with the Vega-Lite API and rendered in D3, with window dimensions providing a full-screen view and tooltips showing the asset name. The `vl.x().fieldT('date')` and `vl.y().fieldQ('close')` encodings map date and price, while the configuration adjusts axis and label styling for readability.
