France population
This choropleth map shows the population of French metropolitan and overseas departments, with each region filled with a color corresponding to its total population. A threshold color scale maps population counts to a blue sequential palette, and a legend with an axis explains the color-to-value mapping. The visualization uses D3 v3, TopoJSON, and a queue to load the geographic data from `france.json` and population figures from `population.csv`. Geographic paths are rendered as SVG via `d3.geo.path` and an Albers projection, and coloring is applied by matching department names between the two datasets.
