This interactive choropleth map visualizes the percentage change in tree cover from 2000 to 2010 across countries. A dropdown menu filters the data by a minimum tree-coverage threshold, from 0% to 75%. The map uses a red-yellow-green diverging color scale to indicate losses and gains, with a mislabeled legend showing 'No Change' for a 50% gain. Built with d3.geoPath, d3.csvParse, and d3.flatRollup, it fetches GeoJSON from the Visionscarto World Atlas and county-level CSV data from a GitHub gist.

AI-generated description

This project update shows the change in forest coverange from 2000 to 2010. The menu allows users to toggle the density - e.g. a threshold coverage of 30% shows the change in area of forest where 30% or greater tree coverage.

Project Momentum IV

This choropleth map visualizes changes in forest coverage between 2000 and 2010, with a dropdown menu letting users filter by varying tree-canopy density thresholds (from 0% to 75%). Each country is colored along a red-yellow-green diverging scale (via `interpolateRdYlGn`) to indicate whether that nation gained or lost forested area at the selected threshold. The map is rendered using `d3.geoPath` and `d3.geoNaturalEarth1` projections, with country shapes loaded from a TopoJSON world atlas and forest-loss data fetched from a CSV file.

Project Momentum V

This map visualizes changes in forest cover from 2000 to 2010, with a menu allowing users to toggle the tree coverage threshold that defines forested area. Each country is colored according to its computed percentage gain or loss of tree cover using a red-yellow-green scale. The visualization loads country boundaries from a TopoJSON world atlas and processes tabular CSV data on tree cover extent by country and year. It uses `d3.geoPath` and `d3.geoNaturalEarth1` for map projection and rendering, `d3.csvParse` for data ingestion, and `d3.interpolateRdYlGn` for color encoding.

Project Momentum III

This visualization maps changes in forest coverage from 2000 to 2010 across countries, with a dropdown menu to adjust the tree-coverage threshold (e.g., 30%) that defines what counts as forest. The map uses a red-yellow-green color scale to indicate the percentage change in forested area, tinting each country accordingly. Built with D3.js, it fetches topojson country outlines via `d3.geoPath` and a natural Earth projection, while parsing CSV data for the coverage deltas. The menu uses D3’s data join to update the threshold and redraw the map.

Project Momentum

This visualization shows a choropleth map of global tree cover loss between 2000 and 2010, using a natural Earth projection. Country boundaries are rendered as SVG paths via `d3.geoPath` and `geoNaturalEarth1`, with each country filled by an `interpolateRdYlGn` color scale based on the percentage change in forest extent per country area. The data comes from a CSV of County Tree Cover Loss, fetched and parsed with `d3.csvParse`, while country geometries are loaded from a TopoJSON world atlas and converted with `topojson-client`. Hover styling and interaction are not implemented.

Final Project Momentum

This visualization maps global tree cover loss by country, using a chloropleth color scale from green to red to indicate the percentage change between 2000 and 2010. The code fetches geographic boundaries from the VisionCarto World Atlas and joins them with CSV data on tree cover extent, applying a D3 Mercator projection and `geoPath` for rendering. Country colors are computed with `interpolateRdYlGn` based on the calculated land-area delta, with stroke outlines for boundaries.

Data Viz Final Project: Change in Global Tree Coverage

A choropleth map of global tree coverage change from 2000 to 2010. A dropdown menu filters the visualization by tree-coverage threshold (e.g., 30%), and each country is shaded with a red-yellow-green diverging scale indicating percentage of forest gain or loss. The map uses `d3.geoPath` with Natural Earth data loaded via `topojson-client`; a tooltip and color legend accompany the render. The underlying dataset is a CSV of county-level tree-cover loss, which is aggregated by country before mapping.

Project Momentum II

Project Momentum II visualizes country-level tree cover loss between 2000 and 2010 on a natural Earth projection, coloring each country on a red-yellow-green scale based on computed delta values. It loads geographic data from the visionscarto world atlas and tree cover CSV data, then uses d3.geoPath and d3.geoNaturalEarth1 to render country outlines, with color mapping via d3.interpolateRdYlGn.

Fork of Data Viz Project

This choropleth map visualizes global population distribution using a dark blue color gradient. The map renders world country boundaries with D3’s `geoMercator` projection and `geoPath`, coloring each nation by its population estimate from the world-atlas dataset. Though the code fetches a CSV of tree-cover loss data, the map currently displays population data, not tree cover, as the primary variable. The visualization updates on window resize and includes hover highlighting for countries.
