This scatterplot visualizes the relationship between UV index and solar radiation measurements across multiple weather stations in Buenos Aires (CABA). Each circle represents an hourly observation, with axis labels marking the UV index on the x-axis and solar radiation in watts on the y-axis. The code uses D3 v5 with a linear scale for both axes, rendering SVG circles with low opacity to show overlapping data density. Data is loaded from a CSV file containing meteorological variables, and the chart includes custom axis formatting and grid lines created through the axisBottom and axisLeft APIs.
