This example shows a gapminder-style bubble chart representing global health and economic data for 2007. The visualization maps GDP per capita on the x-axis and life expectancy on the y-axis, with circle size encoding population and colors distinguishing continents. Built with Svelte and d3.js, the code uses d3.scaleLinear, d3.scaleSqrt, and d3.scaleOrdinal to map data values to positions, radii, and fills. Each bubble is rendered as an SVG circle with reduced opacity, driven by data from the Gapminder dataset.

AI-generated description

Task

  • 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

Fork of #Utrecht2024 TASK: First steps in Svelte

This is a scatter plot that compares the GDP per capita and life expectancy of countries for the year 2007, with the size of each circle representing the country's population. The SVG is rendered using Svelte, with a `Datapoint.svelte` component drawing semi-transparent circles. The code uses D3's `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` to map the data to positions, radii, and continent-based colors. The data originates from the Gapminder dataset, which is loaded from a CSV file.

Fork of #Utrecht2024 TASK: First steps in Svelte

A scatterplot shows countries positioned by GDP per capita and life expectancy, with circle size encoding population and color distinguishing continents. The Svelte app formats the data with `autoType` from d3, computes scales with `scaleLinear`, `scaleSqrt`, and `scaleOrdinal`, and renders SVG circles via a custom Datapoint component. Data comes from the Gapminder dataset, though the example uses 2007 values.

Fork of #Utrecht2024 TASK: First steps in Sveltenew

This example shows a scatterplot of countries, with each country represented by a circle whose position is determined by GDP per capita on the x-axis and life expectancy on the y-axis, and whose size reflects population. The circles are colored by continent, and the data is sourced from Gapminder. The visualization maps data using `d3.scaleLinear` for the axes, `d3.scaleSqrt` for the radius, and `d3.scaleOrdinal` for the categorical color scale. It renders circles as SVG elements, with the entire plot dynamically generated in the Svelte component.

Steven #Utrecht2024 TASK: First steps in Svelte

This example creates an interactive bubble chart plotting life expectancy against GDP per capita, with bubble size encoding population and color distinguishing continents. It includes a tooltip that appears on hover, revealing the country name. The visualization is built with Svelte components using d3's `scaleLinear`, `scaleSqrt`, `scaleOrdinal`, and `schemeAccent` for scales, and a Voronoi overlay from `Delaunay` for efficient hover detection. Data is loaded from a CSV file and rendered as SVG circles.

Fork of Fork of #Utrecht2024 TASK: Tooltips/Voronoi

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.

Fork of #Utrecht2024TASK: Voronoi and Tooltips reactive

This visualization displays global health and economic data for 2007, plotting life expectancy against GDP per capita for each country. The circle size encodes population, and color denotes continent. A reactive tooltip appears on hover, displaying the country's name against its colored background. Built with Svelte and rendered as SVG, the example uses d3's `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` for positioning, sizing, and coloring. It employs the `Delaunay` class from 'd3' to compute a Voronoi overlay, whose invisible paths capture mouse events to update the tooltip.

Fork of #Utrecht2024 TASK: First steps in Svelte

This example demonstrates a minimal Svelte setup for processing Gapminder data. It displays the raw dataset as JSON text after converting data types with `d3.autoType`, ensuring that numeric fields like population and GDP are parsed as numbers rather than strings. The visualization uses Svelte's reactive bindings to track the container's dimensions, though the current view shows no chart or filtering. The code reads from a CSV file and outputs the structured data directly, serving as a foundation for building more complex bubble charts with the library.

Fork of #Utrecht2024 TASK: Voronoi and Tooltips

A bubble chart shows life expectancy against GDP per capita for countries in 2007, with circle size representing population and color encoding continent. Hovering over any bubble displays a tooltip with the country name. The visualization uses d3.scaleLinear, d3.scaleSqrt, and d3.scaleOrdinal for scales, while d3.Delaunay generates Voronoi cells that overlay the chart to capture mouse events for each data point, triggering the tooltip display.
