This example shows a line chart of stock closing prices over time, where the line is colored by value using an SVG linear gradient. The gradient maps price levels to colors: low values appear red, middle values black, and high values lawngreen. A light gray line and axis frame the chart, while the data is loaded from a CSV with dates and closing prices. Although tooltip and scatterplot code are present, they are commented out, so the visualization displays only the gradient-colored line without animation. The gradient is defined vertically over the y-axis range, creating a smooth color transition that highlights the price thresholds directly on the line.
