This example generates a heatmap visualization of Euclidean distances from a central point, computed over a grid of x and y coordinates. The color-coded matrix uses the "Jet" colorscale, with axes hidden to focus on the radial pattern. The page leverages the Plotly JavaScript API (plotly-2.16.1) to render the heatmap and export it as an SVG image, while also including D3.js v3.5.17 as a dependency, though it is not directly used in the plotting logic.
