This visualization maps urban population growth from 2015 to 2030 using a globe with dots positioned by latitude and longitude from cities.csv. Canvas rendering draws the world map and animated growing circles sized by projected population, while SVG overlays provide hover interactivity. D3 v4 powers the geographic projections and data-driven transitions, with each city represented by a circle that scales from its 2015 to 2030 population estimate, offering a comparative view of urban expansion across countries.
This visualization animates a global map of urban population growth, plotting 2015 and 2030 projections for cities as linked circles. Using D3 v4, it renders an SVG world map and projects city coordinates onto a canvas, with each city represented by a circle whose radius encodes population. A transition animates the circles between the two years, and a legend, likely with a color scale, distinguishes 2015 from 2030 values. Hover interactions may reveal city details.
