A choropleth map of French regions shows the cumulative total of influenza cases reported during 2014, with each region colored on a white-to-green scale based on its annual sum. The visualization combines a conic conformal projection with `d3.geoPath` to render regional boundaries from a GeoJSON file, while `d3.csv` loads weekly case counts from a CSV. A linear color scale (`d3.scaleLinear`) maps the maximum annual total to the darkest green, and region polygons are colored by matching names between the CSV and GeoJSON properties.

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.

A choropleth map displays the annual sum of influenza cases across French regions in 2014, colored on a white-to-green scale. Hovering over a region reveals its name and total count via a tooltip. Built with d3.v4, it uses `d3.geoOrthographic` projection, `d3.geoPath` for rendering GeoJSON, and `d3.scaleLinear` for color mapping. Data comes from the GrippeFrance2014.csv file, merged with regional geometries from regions.json.

TP4_France

A choropleth map of France colors each region by the total reported influenza cases for 2014, using a quantized green color scale. The visualization reads regional totals from a CSV file and joins them to geographic features from a local GeoJSON file via `d3.csv` and `d3.json`. D3 v4’s `d3.geoConicConformal` projection and `d3.geoPath` render the map, while `d3.scaleQuantize` maps data values to fill colors, with missing regions shown in gray.

TP 4: Donnees spatiales

A choropleth map of France shows the total number of influenza cases reported in 2014 for each region, using a five-color quantized scale ranging from light purple to dark green. The visualization merges data from a CSV file containing weekly case counts with a GeoJSON file of French regional boundaries, assigning the annual sum to each region. Built with D3 v3, the map uses a conic conformal projection and the `d3.geo.path` API to render the regions, with the color domain fixed from 0 to 2000 cases. Regions lacking data appear gray.

TP4 DATAVIZ

A choropleth map of France colors each region according to its total reported influenza cases for 2014, using a five-step green color scale. The map is drawn with `d3.geoPath` and a `d3.geoConicConformal` projection, while case totals from the CSV file are joined to region geometries by matching region names. Regions without matching data are filled gray. The visualization is built with D3 v4 and renders static SVG paths.

TP4

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.

This visualization shows the annual incidence of influenza across French regions in 2014, using a choropleth map with an orthographic projection. Regional totals are aggregated from weekly case counts and displayed as colored polygons, with a tooltip showing each region’s name and total. The map is rendered using `d3.geoOrthographic()` and `d3.geoPath`, with regions colored via a linear scale from white to green and hover interactions managed through D3 event handlers. Data is parsed from a CSV file and joined to GeoJSON features.
