This interactive D3.js map displays the state of Texas with its county boundaries, major city markers, and labels. Built with D3 v7 and TopoJSON, it uses d3.geoMercator and d3.geoPath to project geographic data from the US-Atlas TopoJSON files. The map renders as SVG, with county paths colored sequentially using d3.scaleSequential and d3.interpolateGreens, while hover effects and tooltips reveal county FIPS codes.

Texas State Map With Zip Codes

This interactive map of Texas displays counties, ZIP code boundaries, and major cities with pan, zoom, and layer-toggle controls. Built with D3.js v7 and TopoJSON, it renders geographic data through the `d3.geoPath` projection and supports custom GeoJSON/TopoJSON ZIP code uploads. Animated loading indicators and hover tooltips enhance the experience. Data sources include the US Atlas TopoJSON for state and county boundaries, plus OpenDataDE ZIP code collections.

Fork of Texas State Map

A Texas state map displays county boundaries colored with a sequential green scale plus overlaid ZIP code outlines. Hovering reveals county FIPS codes and ZIP code names. The visualization uses d3.geoMercator, d3.geoPath, and topojson to render US Census Bureau state and county data, with ZIP codes from an ArcGIS REST service. A file input button allows uploading custom GeoJSON or TopoJSON data.

USA Map Visualization

This example displays a map of Texas, colored according to a sample state population dataset. The code uses D3.js v6 with an SVG rendering approach. It loads GeoJSON map data from a local TX.geo.json file and applies a `d3.geoAlbersUsa` projection with `d3.geoPath` to draw the state boundary. A sequential red color scale (via `d3.scaleSequential` and `d3.interpolateReds`) maps population values to fill colors. States not found in the dataset appear light gray.

Texas Private and Public Universities

This D3.js v7 visualization maps the locations of public and private universities across Texas using ZIP codes, with blue and red markers distinguishing institution types. It renders an SVG map of Texas via d3.geoPath and topojson.v3, plotting university coordinates with circle markers. Hover tooltips display each university’s name, city, and ZIP code, while permanent labels identify institutions directly on the map. The visualization uses hard-coded latitude and longitude coordinates from the included dataset, with mouseover and mouseout event handlers controlling tooltip visibility and marker emphasis.

Assignment 8 STAAR Test Results Map in Texas

This choropleth map displays county-level STAAR test performance across Texas, with each county shaded on a sequential orange-red color scale based on its standardized test score percentage. The visualization uses d3.geoPath with a geoAlbersUsa projection to render Texas counties from TopoJSON data, while test scores are joined via a Map from CSV data. Hovering reveals a tooltip with the county FIPS code and score, and a legend with a linear gradient shows the color-to-value mapping. The code relies on d3.v7, topojson, and d3.scaleSequential with d3.interpolateOrRd.

Assignment 8 STAAR Test Results Map in Texas2

A choropleth map displays county-level STAAR standardized test performance percentages across Texas, with orange-to-red shading representing score ranges and gray indicating missing data. The visualization uses d3.geoMercator projection and d3.geoPath to render Texas counties from a TopoJSON atlas, filtered by FIPS codes starting with 48. Unemployment data from a Plotly GitHub CSV serves as proxy test scores, loaded via Promise.all with d3.json and d3.csv. Interactive tooltips appear on mouseover, while a gradient legend with a linear scale communicates the color mapping.

Assignment2_question6

This example displays a map of Texas rendered as an SVG using D3.js version 5. It loads U.S. state boundaries from the `us-atlas` TopoJSON file hosted on a CDN, then extracts the geometry for Texas using the `topojson.feature` API. The map is projected with `d3.geoAlbersUsa` and drawn with `d3.geoPath`, resulting in a single-path visualization of the state outline. The code selects the body element and appends an SVG canvas sized 960 by 500 pixels to display the final geographic shape.

US States Map

This example renders a geographic map of US states using D3 and TopoJSON, loading data from the us-atlas TopoJSON file. It draws each state with `d3.geoPath` and a `geoAlbersUsaTerritories` projection, which includes US territories. State boundaries appear as white strokes overlaid via a TopoJSON mesh, while the map updates reactively through the `d3-rosetta` StateProperty pattern. The visualization highlights the separation between states and provides a clean, basic template for choropleth or interaction extensions.
