A physics-inspired financial simulation visualizes a dual-directional leveraged bond (dDLB) as an animated line chart tracking notional value and reinvestment coupon components over time. The black background features a white radial gradient circle that follows the mouse cursor, displaying "Hello World!" text. Using D3.js v7 with SVG rendering, the simulation runs a 10-millisecond interval, applying inflation and deflation volatility models with normally distributed random values to update the chart paths dynamically.
