This interactive scatter plot visualizes the relationship between dew point and relative humidity for weather data. Each point represents a day, and the chart uses a Voronoi diagram to define hover regions around each point, making it easier to select and inspect individual data points. The visualization, rendered as an SVG using D3.js v5 and the d3-delaunay library, displays a tooltip with the exact date, humidity, and dew point values upon mouseover. The data is loaded as JSON and plotted using linear scales for both axes.
