A choropleth map of French regions shows the weekly incidence of influenza-like illnesses during 2014, with a slider to step through the year and a tooltip on hover. The map uses d3.geoConicConformal and d3.geoPath to render region boundaries, while a d3.scaleQuantize maps case counts to a five-color scale. Data is loaded from a CSV and joined to GeoJSON features, with the legend displayed as colored rectangles.

A choropleth map of French administrative regions shows weekly influenza case counts from 2014, aggregated by region. A slider lets viewers scrub through the 52 weeks of the year, updating the map’s fill colors. Built with D3 v4, it uses `d3.geoConicConformal` for projection, `d3.geoPath` for rendering GeoJSON regions, and `d3.scaleQuantize` for color encoding. Data is loaded from a CSV file, with weekly values parsed via `d3.timeParse` and hover tooltips displaying the region’s name and current value.

This choropleth map displays the cumulative number of influenza cases across French regions for the weeks of November 2014. Each region is colored on a five-step green scale, with darker shades indicating higher totals, and hover tooltips reveal exact values. The visualization merges CSV data with geographic boundaries using D3’s `d3.geo.path` with a conic conformal projection, while `d3.scale.quantize` maps data values to the color range. The code also demonstrates layering multiple GeoJSON loads and integrating mouse events for interactive detail.

A choropleth map of France displays the cumulative seasonal count of influenza cases for each region in 2014, colored from white to green on a linear scale. The visualization loads regional data from a CSV file and geographic boundaries from a GeoJSON file, then merges them. It uses `d3.geoConicConformal` and `d3.geoPath` to draw the regions, while a D3 linear scale with an HCL interpolation maps the summed yearly values to the color range. Hovering over a region reveals its name via a tooltip.

This choropleth of French regions displays the weekly incidence of influenza for November 2014, with color intensity mapped to the sum of reported cases for those weeks. Built with D3 v4, the visualization uses `d3.geoConicConformal` for projection, `d3.geoPath` to render the map from a GeoJSON file, and `d3.scaleQuantize` to assign chromatic classes. Values are loaded from a CSV containing weekly regional data, and a tooltip appears on mouse-over to reveal the specific regional total.

This interactive choropleth map displays weekly influenza case counts across French regions for 2014. A slider lets users step through each week, updating region colors through a quantile scale. The visualization uses D3 v3 with `d3.geo.conicConformal` for projection, `d3.geo.path` for rendering GeoJSON regions, and a custom tooltip on mouseover. Data comes from the GrippeFrance2014.csv file containing weekly regional counts.

A choropleth map of France displays regional influenza consultation data for 2014, with each region colored on a green sequential scale according to weekly or monthly case counts. The visualization uses D3 v4 with `d3.geoConicConformal`, `d3.geoPath`, and `d3.scaleQuantize` to render SVG paths from the `regionsFrance.json` GeoJSON file, while a CSV file provides the data. Hovering over a region reveals a tooltip with its value.

A choropleth map of French regions visualizes weekly influenza case counts across 52 weeks in 2014, with a slider to navigate through time. The map’s fill colors are assigned from a five-step quantize scale based on the selected week’s value, and hovering over a region shows a tooltip with its name and count. Built with D3 v4, the visualization binds CSV data to a GeoJSON topology, renders regions using `d3.geoPath` with a conic conformal projection, and updates the `style.fill` dynamically on slider input.

A choropleth map of metropolitan France displays weekly influenza case counts by region for 2014, with a slider to navigate through the year. The visualization uses d3.geoConicConformal for map projection and d3.geoPath to render regional boundaries, with fill colors assigned via d3.scaleQuantize. A hover tooltip shows the region name and case value. Data comes from the GrippeFrance2014.csv file, which is merged with the france.json GeoJSON structure.
