A black canvas responds to mouse movement by tracking the cursor with a glowing radial-gradient circle and a white text label reading “3v@n.” Simultaneously, an animated white line chart grows from left to right, plotting a random walk that meanders vertically across the screen. The visualization uses D3 v7 to manage SVG elements, with event handlers on `mousemove` and `click` updating the cursor marker, while a `setInterval` drives the chart’s incremental path construction and opacity fade.
