New York Map

New York Census Tracts Demographics: White

This visualization shades New York census tracts by the number of white residents, using a green sequential scale where darker greens indicate higher counts. The map loads TopoJSON geometry and American Community Survey demographic data fetched from a GitHub gist, then joins the data to each tract. It renders SVG paths with `d3.geoPath`, applies an `interpolateGreens` color scale via `scaleSequential`, and supports pan and zoom through `d3.zoom`. Hovering over a tract logs its properties to the console.

Fork of WIP New York Census Tracts Demographics

This visualization displays demographic data for New York Census Tracts, coloring each tract by its white population count using a sequential green color scale. The map is rendered as an SVG using d3.geoPath, with the geographic boundaries provided by TopoJSON. Population data comes from the American Community Survey API, which is fetched asynchronously and merged with the tract geometries. Users can pan and zoom the map via d3.zoom, and hovering over a tract logs its properties to the console.

Broken New York Census Tracts Demographics

This example shows New York State census tracts colored by their white population count using a green sequential color scale. The visualization maps demographic data from the 2018 American Community Survey API onto census tract polygons, which are rendered using `d3.geoPath` with a null projection. The code combines `d3.json` and `d3.tsv` for data loading, TopoJSON for feature extraction, and `d3.scaleSequential` with `interpolateGreens` for color encoding. However, the visualization is incomplete, as the code logs console output for hovered tracts but does not display tooltips or a legend, and the color mapping may fail due to mismatched tract IDs between the TopoJSON and ACS data sources.

New York Census Tracts

A map of New York State census tracts appears in gray, with orange highlighting on hover and dark borders outlining each tract. The visualization uses D3.js (v3) with TopoJSON to load and project geographic data from `ny.json`, and `d3.geo.path()` converts the topology features into SVG paths. The data is filtered to exclude water counties, and tract IDs are displayed as tooltips.

Opacity Linear Scale

This visualization maps New York census tracts, using a green color scale to represent the white population density—the greener the tract, the more white residents it has. The data comes from the American Community Survey API, joined with TopoJSON geometry from a GitHub gist. The code uses d3.scaleLinear to map white population counts to an opacity range, creating a semi-transparent overlay, while d3.geoPath renders the tract shapes and d3.zoom enables pan and zoom interaction.

New York Census Tracts

A choropleth-style map of New York census tracts renders all tract polygons in gray, with tract borders drawn in dark gray to reveal the state's internal administrative divisions. The visualization loads pre-projected TopoJSON geographic data (`ny.json`), which the code trims by excluding water-only county rows. Using d3.geo.path with a null projection for rendering and topojson.feature to convert the geometry, the map displays tract IDs as SVG title tooltips on hover. The style uses default light gray fills for each tract polygon.

New York Census Tracts Demographics: Black

This visualization maps New York State census tracts and uses a sequential orange color scale to encode the population identifying as Black or African American. The map is rendered as SVG with `d3.geoPath` on top of TopoJSON data, and the demographic values come from the 2018 American Community Survey API. Zooming and panning are enabled via `d3.zoom`, and hovering highlights individual tracts. The color scale uses `d3.scaleSequentialSqrt` with `interpolateOranges`, where darker orange indicates higher Black population counts.

New York Census Tracts Demographics: Black

This visualization maps New York census tracts, using the intensity of orange to represent the population identifying as Black or African American, from 2018 American Community Survey data. It displays tract polygons rendered with `d3.geoPath` in an SVG, colored by a sequential scale using `scaleSequential` and `interpolateOranges`. The code loads TopoJSON geometry and ACS data via `Promise.all`, then maps each tract to its demographic values, with hover highlighting and zoom support via D3’s zoom behavior.
