This scatter plot visualizes the relationship between microwave and office lighting power consumption, using a semi-transparent line mark to reveal density patterns in the data. The visualization is built with the Vega-Lite API, which translates specifications into Vega and renders as SVG. Data is loaded asynchronously from a CSV file using `d3.csv`, with the plot dimensions automatically fitting the browser window. Visual styling for axes and labels is customized through a separate configuration object, and interactive tooltips are enabled via the vega-tooltip handler.
