A hybrid visualization combines a scatter plot with circle packing to represent hierarchical sound design data. Using D3 v5 within a React framework, the SVG scene maps top-level sound categories (like Clap or Gunshot) as scatter points positioned by `xRange` and `yRange` scales, with nested child layers packed via `d3.pack`. Interactive hover events display sound names, while click events increment a visual counter. The interface integrates audio playback controls and a timer, though the core focus remains the layered spatial encoding of sound file relationships.
