points on atlas
This visualization displays city population data as red circles plotted on a natural Earth projection world map. The map shows land masses in gray with white graticule lines and country borders. Circle radius encodes population using d3.scaleSqrt. The implementation uses d3-geo for the projection and path generation, topojson for world atlas data, and React for rendering SVG elements. City data comes from a CSV file loaded via d3.csv, while geographic boundaries come from the world-atlas TopoJSON dataset.
AI-generated descriptionThis bar chart shows population of the top 10 most populous countries. The data comes from the year 2018 estimate in United Nations: World Population Prospects 2017. It also demonstrates customization of D3 axes.
