This interactive bubble chart displays Gapminder data from 2007, plotting countries by GDP per capita against life expectancy, with circle size encoding population and color distinguishing continents. A Voronoi overlay, generated using `Delaunay` from D3, enables precise hover detection between overlapping bubbles. Hovering a region displays a tooltip with the country name and its assigned color. The visualization is built with Svelte components and SVG, using D3 scales including `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` to map data attributes.
AI-generated descriptionTask
- format the data: numbers should be numbers – not strings
- filter and only use data of the year 2022
- determine the min and max value of GDP and life expectancy
