This interactive visualization compares health and wealth indicators—population, income, and life expectancy—across two selectable countries. Users choose a data category and two countries from dropdown menus, and the chart renders dual blue and pink line paths to compare trends over time. Built with D3 v4, the code uses `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to map year and value domains from the nations dataset to an SVG canvas; `d3.extent` and `d3.merge` derive the axis ranges. The source data is embedded in a JSON file.

wealth & health of nations

This scatterplot, titled “wealth & health of nations,” visualizes the relationship between income per capita and life expectancy across countries. Each circle represents a nation, positioned along a logarithmic x-axis for income and a linear y-axis for life expectancy. Hovering over a circle displays a tooltip with the country’s name. The chart includes labeled axes for "Income per capita" and "Life Expectancy," and the D3 v4 code uses an SVG and animation to render the data.

The Wealth & Health of Nations

This interactive scatterplot animates 209 years of global development, tracing each nation’s per-capita income (x-axis), life expectancy (y-axis), and population (circle radius) across time. Clicking and dragging the year slider scrubs forward and backward through the dataset, with circles colored by geographic region. The visualization uses D3 v3’s scales (log, linear, sqrt), axes, and transitions, interpolating sparse historical data from Gapminder via linear interpolation and bisection. Rendered as animated SVG elements, it recreates Hans Rosling’s famous 2006 TED talk visualization.

Health and Wealth of Nations - Bubble Chart

A bubble chart displays the relationship between life expectancy and income for nations, using population for bubble size and region for color. The data comes from a JSON file loaded via `d3.json`, and the chart is rendered with d3fc’s cartesian chart, logarithmic x-scale, and linear y-scale. A point series with a linear size scale creates the bubbles, while a legend from `d3-legend` is positioned over the SVG plot.

A Re-Recreation of Gapminder’s Wealth & Health of Nations - Romain Vuillemot

This interactive scatter plot recreates the classic Gapminder visualization, mapping countries as circles over time, with income per capita on the x-axis, life expectancy on the y-axis, and population encoded by circle radius. Users can drag any country circle to explore its historical trajectory, which is drawn as a gray path connecting its annual data points. The code uses D3.js v3 for SVG rendering and animation, with a custom `dragit.js` library handling the drag-and-drop interaction and trajectory display. Data is loaded from a local `nations.json` file, and a slider lets viewers scrub through years from 1800 to 2008.

CS171 - Health & Wealth of Nations

A scatterplot shows the relationship between national income and average life expectancy across countries, with bubble size representing population and color indicating world region. The visualization loads data from a CSV file and renders circles in an SVG using D3 v5, applying logarithmic and linear scales to map income and life expectancy. Animated transitions are not present, but the chart includes axis labels and a legend-less ordinal color scale for categorical region data.

This example visualizes global health and wealth data by plotting circles for each country on logarithmic and linear scales. The x-axis shows GDP per capita (wealth), the y-axis shows life expectancy (health), and circle radius encodes population size, with colors representing continents. The visualization is built with D3 v4, using SVG rendering, and employs `d3.scaleLog`, `d3.scaleLinear`, and `d3.scaleSqrt` for positioning and sizing. Data is loaded from a CSV file, with axes labeled in French for per-capita income and life expectancy at birth.

This example visualizes global health and wealth data as a bubble chart, where each circle represents a country positioned by life expectancy (y-axis) and GDP per capita (x-axis), with circle size encoding population and color encoding continent. It uses D3 v4’s scales (`scaleLinear`, `scaleLog`, `scaleSqrt`, `scaleOrdinal`) to map variables and renders SVG circles with axes labeled accordingly. The code loads CSV data via `d3.csv` and applies sorting by population, while styling uses opacity and a light grey background. The chart focuses on comparing country-level indicators, with axes labeled in French.

Basic Scatter Plot

This scatter plot visualizes the relationship between income per person and health expectancy across countries, with circle size encoding population and color distinguishing world regions. Data comes from the World Wealth & Income Database and the Global Health Observatory. The visualization uses d3.scaleLog for the income axis, d3.scaleLinear for health, and d3.scaleSqrt for population-based circle radii. SVG rendering includes custom axes with gridlines and a categorical color legend built with d3.legendColor.
