  /**
   * Angular port of the UIPKGE BubbleMap. React/Vue render Mapbox-backed proportional symbols with legend, selection and projection controls; this standalone port renders a dependency-free ECharts scatter overview (no Mapbox token needed) with the same square-root area normalization in a pure getOption(). Shared inputs: `bubbles`, `minRadius`, `maxRadius`. The Mapbox-only inputs (`showLegend`, `legendTitle`, `selectedId`, `interactive`, `projection`, `variant`, `center`, `zoom`) and selection outputs are intentionally dropped; `height` / `option` / `ariaLabel` follow the other Angular ECharts ports.
