This visualization shows a choropleth map of the United States, displaying the number of clean energy jobs per 1,000 workers. The map uses a green sequential color scale with threshold breaks, allowing viewers to compare state-level employment data at a glance. The visualization is built with d3.v7, using `d3.geoAlbersUsa()` for projection and `d3.geoPath()` to render state boundaries. It loads data from a CSV file via `d3.csv` and U.S. state boundaries from the us-atlas TopoJSON, while `d3.scaleThreshold()` assigns colors based on job density values. Hovering over a state reveals a tooltip with its specific data.

Assignment8_Manisha_USMap

This choropleth map displays US state unemployment rates, with each state colored on a sequential blue-purple scale (d3.interpolatePuBu) according to its percentage. The visualization loads state boundaries from the us-atlas TopoJSON file and joins CSV data containing state names and unemployment values. Hovering over a state reveals a tooltip showing the state name and its unemployment rate or “N/A” for missing data. The map uses d3.geoPath with a d3.geoAlbersUsa projection and renders as SVG, with states encoded as paths and tooltip positioning handled via mouse events.

USA Map

This visualization displays a choropleth map of the United States, where individual states are filled with varying intensities of red based on values loaded from a CSV file. States without matching data appear in gray. The map is rendered as an SVG using D3.js, with geographic boundaries drawn via `d3.geoPath` and TopoJSON features from the `us-10m.v1.json` dataset. A `d3.scaleLinear` maps data values to a color range from light red to deep red for each state's fill.

US MAP

This interactive visualization displays a choropleth-style map of the United States, rendered as an SVG using React and D3 v5. The map shows state boundaries through purple interior lines, with land areas filled in green against a dark blue sphere background. The code employs `d3.geoAlbers` for the Albers equal-area projection, `d3.geoPath` to generate SVG paths, and `d3.geoGraticule` for grid lines. Geographic data comes from the `us-atlas` TopoJSON file, processed through `feature` and `mesh` from topojson library.

Assignment8_sowjanya_countryMap

A choropleth of the United States displays median age by state, using a pastel threshold color scale with seven bins ranging from under 32 to over 46 years. The visualization loads US Census-derived CSV data and TopoJSON state boundaries via `Promise.all`, then renders each state as an SVG `path` using `d3.geoPath` with the `geoAlbersUsa` projection. Hovering reveals a tooltip with the state name and median age, while a horizontal legend beneath the map shows the color breaks. The code relies on D3 v7 and the topojson-client library.

USA Map

This choropleth map of the United States colors each state according to a numeric value loaded from a CSV file, using a linear lightred-to-red scale. The SVG rendering is built with d3.geoPath, which projects the US states from a GeoJSON file, while topojson.feature extracts the state features. State FIPS codes from the CSV are matched against the GeoJSON IDs to assign fills, with gray as the default for missing data. The visualization relies on d3.select, d3.csv, and d3.json for data loading.

US Map

A choropleth map of the United States colors individual states by population, using a threshold color scale that ranges from light yellow to dark amber. The visualization loads US state boundaries from the us-atlas TopoJSON file and renders them as SVG paths via d3.geoPath with an Albers USA projection. Population values are mapped to FIPS codes using a JavaScript Map, and the d3.scaleThreshold assigns fill colors based on population brackets. Hovering over a state triggers a native SVG title tooltip displaying the FIPS code and population figure.

USA Country Map

This example displays a choropleth-style map of the 50 U.S. states, with each state filled in sky blue and separated by black borders. The visualization shows the geographic boundaries of the states, and hovering over a state highlights it in a warm orange color. The map is rendered as an SVG using React, with D3’s `d3.geoPath` and the `geoAlbersUsaTerritories` projection to convert TopoJSON data from the `us-atlas` package into drawable paths. The geometric data is loaded via `d3.json`, and state boundaries are computed using TopoJSON’s `feature` and `mesh` functions.

Assignment 2 USA map

This example displays a choropleth-style map of the United States rendered as SVG paths. The code uses D3 v5’s `d3.geoAlbersUsa` projection and `d3.geoPath` to convert GeoJSON features into map outlines, with each state filled red and stroked blue. The geographic data comes from a remote US features JSON file fetched via `d3.json`. The visualization sets a fixed 700×700 canvas and demonstrates D3 map projection, path generation, and asynchronous data loading in a single page.
