Though thematic mapping had its origins in the 19th century, the technique is useful for understanding history in our own day. One of the fundamental problems of history is scale: how can historians move between understanding the past in terms of a single life and in the lives of millions; within a city and at the bounds of continents; over a period of days and over the span of centuries? Maps can't tell us everything, but they can help, especially interactive web maps that can zoom in and out, represent more than one subject, and be set in motion to show change over time.
To help show the big patterns of American slavery, I have created an interactive map of the spread of slavery. Where the Coast Survey map showed one measure, the interactive map shows the population of slaves, of free African Americans, of all free people, and of the entire United States, as well as each of those measure in terms of population density and the percentage of the total population. The map extends from the first Census in 1790 to the Census taken in 1860 on the eve of the Civil War. You can explore the map for yourself, but below I have created animations to highlight some of the major patterns.

This interactive map and the Census data on which it is based can hardly show most of what should be known about slavery. For example, the Census did not count any slaves in Vermont, which abolished slavery in its 1777 constitution. But Harvey Amani Whitfield has shown that some Vermont African Americans were held in bondage. Nor can these maps express anything of the pain of the whip or the escape to freedom, of the exhaustion of labor or the sounds of preaching and shouting at a religious gathering: for that one must read any of scores of excellent histories. But they do give a large overview of the forced labor system which made the nation "half slave and half free."
The map above reveals the results of our annual data mining, the top 3 most popular Halloween candies in each state. Hover over your state to see the goods. (Apologies, it's not interactive on mobile devices).
Then we charted the best sellers in every state for Halloween. And we present it to you in the above futuristic interactive map of the most popular Halloween candy. If you'd like to see the nationwide winners, we made a graphic for that too:
We want to know where infections are trending up or down relative to the size of the outbreak in each country. So in these charts we use a rolling 7-day average of the new infections countries report each day and compare where that average is now to where it was at its peak.
A new study reveals the full extent of globalization in the world's food supply. The researchers put together a series of interactives that visualize the results. Here's a screen grab, which shows crops that originate in South Asia. Click here to see more interactive maps. Screenshot from CIAT hide caption
This screenshot of an interactive graphic shows that, on average, crops that originated in tropical South America contribute 821.6 calories per person per day to West African diets. See more interactive maps. Screenshot from CIAT hide caption
The goal of our database is to offer an objective perspective on Chinese direct investment in the US by providing an accurate assessment of trends to policy leaders, executives, and the general public in both China and the US, leading to better policymaking and understanding of opportunities and risks. Rhodium, in partnership with the National Committee on US-China Relations, produces public reports and provides additional dimensions for exploring the data on the interactive US-China FDI Project website.
Development Relevance: The World Bank Group is committed to reducing extreme poverty to 3 percent or less, globally, by 2030. Monitoring poverty is important on the global development agenda as well as on the national development agenda of many countries. The World Bank produced its first global poverty estimates for developing countries for World Development Report 1990: Poverty (World Bank 1990) using household survey data for 22 countries (Ravallion, Datt, and van de Walle 1991). Since then there has been considerable expansion in the number of countries that field household income and expenditure surveys. The World Bank's Development Research Group maintains a database that is updated annually as new survey data become available (and thus may contain more recent data or revisions) and conducts a major reassessment of progress against poverty every year. PovcalNet is an interactive computational tool that allows users to replicate these internationally comparable $1.90, $3.20 and $5.50 a day global, regional and country-level poverty estimates and to compute poverty measures for custom country groupings and for different poverty lines. The Poverty and Equity Data portal provides access to the database and user-friendly dashboards with graphs and interactive maps that visualize trends in key poverty and inequality indicators for different regions and countries. The country dashboards display trends in poverty measures based on the national poverty lines alongside the internationally comparable estimates, produced from and consistent with PovcalNet.
