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.

A scatterplot maps average GDP per capita against life expectancy, with circle size encoding population and color indicating geographic region. The SVG visualization uses D3 v4’s `scaleLinear` and `scaleSqrt` to position and size circles, loading data from `gapminder_avg.csv`. Each point is rendered with a black stroke and fill opacity adjusted for overlap, revealing broad correlations between wealth, longevity, and population across nations.

This example visualizes global health and economic trends using a Gapminder-style scatterplot. Each circle represents a country, positioned by life expectancy (x-axis) and fertility rate (y-axis), with circle size encoding population and color representing geographic region. The visualization animates through years 1964 to 2013, showing how countries move across the chart as their metrics evolve. The data, loaded from a CSV, includes fields for country, year, fertility, life expectancy, population, child mortality, and GDP. Using D3 v5 and SVG rendering, the chart emphasizes the relationship between health outcomes and economic development over time, with a transition effect revealing changing distributions across decades. The visualization is minimal and functional, with axes labeling life expectancy and fertility, and a legend for regions.

This example, built with D3 v5 and SVG, visualizes a Gapminder-style dataset using a bubble chart. The x-axis represents GDP per capita, the y-axis shows life expectancy, circle size encodes population, and color maps to geographic region. The chart animates through years 1964 to 2013, showing how countries' development indicators evolve over time. A play button and time slider allow users to scrub through the years, with circles transitioning smoothly between states. The visualization highlights global trends in health and wealth, with tooltips providing country-specific data on mouseover.

This scatterplot visualizes Gapminder data from 1970, plotting fertility against life expectancy for various countries. Each circle’s size encodes population, while its color distinguishes geographic regions. The visualization uses d3.csv to load the data, d3.scaleLinear for the axes, d3.scaleSqrt for circle sizing, and d3.scaleOrdinal with schemeCategory10 for region colors. SVG elements are drawn via d3 selections, with axes generated using d3.axisBottom and d3.axisLeft, and a legend included.

This example animates the classic Gapminder bubble chart, mapping fertility, life expectancy, and population over time. It uses D3 v5 to render SVG circles, with x position encoding GDP per capita, y position encoding life expectancy, and circle size encoding population, while color distinguishes world regions. The chart plays through decades of country-level data, showing how nations move across the socioeconomic landscape as development indicators shift.

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.

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.
