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.

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.

TP4 fini

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.

TP4 suite 3

An animated choropleth map of France displays weekly influenza case counts across regions from 2003 to 2015. A time slider lets users scrub through the weeks, updating each region’s fill color using a threshold color scale. The visualization uses D3 v3 with `d3.geo.conicConformal` for projection, `d3.geo.path` for rendering GeoJSON regions, and `queue()` for loading CSV and GeoJSON data. Hovering over a region reveals its name and current value via a tooltip.

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.

TP4

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.

TP_4_v2

A choropleth map of French administrative regions displays weekly influenza case counts for 2014. A slider updates the displayed week, recoloring each region with a quantized green color scale, and hovering reveals a tooltip with the region name and count. The visualization uses D3 v4 with `d3.geoConicConformal` for projection, `d3.geoPath` for rendering, and loads region boundaries from `france.json` alongside case data from `GrippeFrance2014.csv`.

TP4

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.

An interactive choropleth map visualizes weekly influenza case counts across French regions in 2014 using D3 v4. A slider controls the displayed week, updating region fill colors from a linear color scale representing case numbers, with tooltips showing exact values on hover. The map uses an orthographic projection via `d3.geoPath` and loads geographic boundaries from `regions.json` while parsing CSV data from `GrippeFrance2014.csv`. Missing data renders regions in grey.
