A choropleth-style map of France displays each department as a white polygon with black outlines, based on GeoJSON data from a gist. The visualization uses D3 v3’s `d3.geo.path()` with a `d3.geo.conicConformal` projection, centered on the country and scaled to fit a 600×600 SVG canvas. Departments are loaded from `departments.json` and rendered as SVG `<path>` elements, with no data encoding beyond the geographical boundaries.

France Map

A map of France displays each department as a white polygon with black borders, using a conic conformal projection. The visualization renders the GeoJSON data from `departement.json` with D3 v4, employing `d3.geoPath` and `d3.geoConicConformal` to project the geographic coordinates. The code initializes an SVG and appends a `path` element for every feature in the dataset, setting fill and stroke attributes directly.

France Map

This example displays a choropleth map of French departments, using a Mercator projection to render each region as a colored SVG path with its name label positioned at the centroid. The visualization loads GeoJSON TopoJSON data from a remote URL, processing it with `feature` from topojson, and generates the paths and labels using `d3.geoPath` and `d3.geoMercator`. Fill colors come from `scaleOrdinal` with `schemeCategory10`, while the map’s layout is adjusted via projection translation and scale parameters in d3 v5 within a React framework.

France

This map of France uses a conic conformal projection to display the country’s administrative regions. The visualization renders each geographic feature as a separate SVG path, with the projection centered on the country’s coordinates. Built with D3 v4, the code relies on `d3.geoConicConformal()` and `d3.geoPath()` to transform GeoJSON data into the final map. The geographic data is loaded from a local file named “France.json,” and the resulting paths are drawn without additional styling or interactivity.

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.

Visualiser des données avec D3

This example displays a choropleth map of French administrative departments, coloring each region according to its population size using a sequential red color scale ranging from light to dark hues. The visualization renders the geographic boundaries as SVG paths via D3.js, employing the `d3.geo.path()` and `d3.geo.conicConformal()` projection APIs to transform the GeoJSON data, while population values from a CSV file are mapped to color classes using `d3.scale.quantile()`.

covid en France avec légende!

A choropleth map of France displays cumulative COVID-19 hospitalizations per department, with a white-to-dark-red color scale using a power exponent to emphasize high totals. The visualization uses d3.geoMercator and d3.geoPath to project and draw geographic features from a JSON topology, while d3.scalePow maps the data domain to the color range. Department totals are loaded from a CSV file via d3.csv, and each path includes a title tooltip showing the department name and its value.

Gist 0562486f752206b124480873ad868676

A choropleth map of France colors each region according to its total reported flu cases across 2014, using a green sequential scale to show geographic variation in incidence. The visualization loads weekly case counts from a CSV file and joins them to regional polygons from a GeoJSON file by matching region names. D3 v4’s `d3.geoConicConformal` projection and `d3.geoPath` render the map, while a `d3.scaleQuantize` maps summed annual values to five color classes. Regions lacking data appear gray.

Gist 596274e96e08f79d5a6d5a6b1c37b944

This visualization displays the incidence of influenza across French regions during the 2014 season, with a choropleth map coloring each region based on its total annual case count. The map is rendered using `d3.geoConicConformal` projection and `d3.geoPath` to draw France’s departmental boundaries. Data from a CSV file is joined to a GeoJSON of regional shapes, and the final fill color reflects each region’s summed value. The code also includes a US states GeoJSON, though its use is not demonstrated in the visible implementation.
