This interactive scatterplot displays stock data with price on the x-axis and true value on the y-axis, using colored circles to represent stock types. Users filter the visualization through a dropdown menu for sector selection and jQuery UI sliders that adjust volume and delta ranges. The D3.js code loads data from a CSV file, applies keyed enter/update/exit selections, and includes hover tooltips that highlight individual stocks. The SVG renderer uses d3.axisBottom and d3.axisLeft for axes, with d3.scaleOrdinal for categorical coloring.
