This interactive galaxy visualization displays 2,000 stars arranged in a spiral pattern with a glowing center, representing stellar temperatures through color (white/blue for hot, orange for cool). Stars twinkle automatically, and hovering brightens them while clicking triggers an explosion animation. The code uses React with D3 v7's `scaleLinear` and `randomNormal` functions to position stars, while SVG filters with `feGaussianBlur` create the glow effect on the galactic center and spiral arms.
