Gapminder time series
This visualization animates a time series of life expectancy versus GDP per capita for India and the United States from 1950 to 2008, using circular points sized by population. The chart uses D3 v4 with SVG rendering to draw two distinct bubbles—one per country—and transitions them smoothly across the years, showing how both nations’ health and wealth indicators evolve over time. The x-axis represents GDP, the y-axis life expectancy, and the bubble radius encodes population. A play button and slider control the animation, letting viewers step through each year or run the sequence automatically. The minimal design keeps the focus on the data, though the two bubbles can overlap when the countries' metrics are similar. The data comes from the gapminder subset referenced in the repository, with axes scaled to show the range of GDP and life expectancy across both countries. A legend identifies India and the United States by color, and the current year is displayed prominently in the visualization.</final>
<final>Gapminder time series — animated scatterplot of 1950–2008 life expectancy vs. GDP per capita for India and the United States, built with D3 v4. Each year is rendered as a circle whose position encodes life expectancy (x) and GDP (y), with size mapped to population. A play button animates through the years, letting viewers see the two countries' trajectories diverge over time. Uses an SVG renderer and MIT-licensed code.</final>Gapminder time series
This D3 v4 visualization animates the classic Gapminder chart using a subset of data for India and the United States, 1950–2008. Each frame plots life expectancy against GDP per capita, with circle size encoding population. A play button advances the year, revealing how the two countries’ health and wealth indicators evolve over time. Rendered as SVG.
Built with blockbuilder.org. Data: subset of the Gapminder dataset (via bost.ocks.org/mike/nations/).
