This visualization maps fatal police shootings in the U.S. since 2015, using a dropdown menu to colorize incidents by attributes such as race, gender, threat level, or mental illness. A GeoAlbersUsa projection renders state boundaries via d3.geoPath, while d3.scaleOrdinal assigns colors to data points. Hovering over the legend filters and highlights matching incidents, and a linked bar chart shows counts per category using d3.scaleBand and d3.scaleLinear. Data comes from the Washington Post’s Fatal Police Shootings database, parsed with d3.csv.

AI-generated description

A program that loads and parses some CSV data from the Fatal Police Shootings Database compiled by the Washington Post

I used the U.S. Geo Map of State Boundaries projected using GeoAlbersUsa for the underlying map.

The mapping portion of the project is adapted from Mass School District Boundaries from the DataVis class. The chart and interactive legend portions are adapted from Interactice Color Legend from the DataVis class.

This visualiazation allows the user to explore geographic trends in the data based on interactively selected attributes including flee status, race, gender, threat level, use of a body camera, and signs of mental illness in the victim. Upon selection, the geomapped marks change color to reflect the given value in the underlying data. The chart in the bottom right of the visualization changes with the selection to reflect the overall count of each attribute within the selected category. For a more clear picture of a specific attribute within the selection, hover over the legend to see the geographic distribution.

Fatal Police Shootings In the U.S. Since 2015

This interactive visualization maps fatal police shootings in the U.S. since 2015, using data from the Washington Post. Users can colorize the geospatial points by attributes like race, gender, or flee status via a dropdown menu. A bar chart in the corner displays counts per category, while hovering over the color legend highlights the geographic distribution of a specific value. The map uses `d3.geoAlbersUsa` and `d3.geoPath` for projection, with points rendered as SVG circles and interactivity managed through React state.

Fork of Fatal Police Shootings In the U.S. Since 2015

A map of the United States displays fatal police shootings since 2015, with each incident plotted as a colored circle based on a selected attribute such as race, gender, or flee status. A bar chart in the corner shows the count of events per category, and an interactive legend highlights the geographic distribution of a specific value on hover. The visualization uses React with D3 v5, including `geoAlbersUsa`, `geoPath`, `scaleOrdinal`, and `scaleBand`, loading data from the Washington Post’s Fatal Police Shootings database and state boundaries from a TopoJSON atlas.

Fatal Police Shootings Category Selection

This interactive map displays fatal police shootings across the United States, allowing users to color-code incidents by attributes such as race, gender, or flee status via a dropdown menu. The visualization uses d3.geoPath with a geoAlbersUsa projection to render state boundaries from TopoJSON data, while circles representing incidents are positioned using the same projection. A d3.scaleOrdinal color scale maps categorical values, with a React-based ColorLegend component showing the corresponding categories. Data comes from the Washington Post’s Fatal Police Shootings database, loaded and cleaned via d3.csv.

Fork of Fatal Police Shootings In the U.S. Since 2015

This interactive visualization maps fatal police shootings in the U.S. since 2015, overlaid on state boundaries projected with `d3.geoAlbersUsa` and rendered as SVG paths. Users can colorize the points by attributes like race, gender, or threat level via a React dropdown, and hover over the ordinal color legend to fade unrelated points. A bar chart using `d3.scaleBand` and `d3.scaleLinear` shows event counts per selected category. Data comes from the Washington Post’s CSV, parsed with `d3.csv`, while state geometries load via `d3.json` and `topojson.feature`.

This interactive visualization maps fatal police shootings in the U.S. since 2015, using the Washington Post’s dataset overlaid on state boundaries via `d3.geoPath` and `geoAlbersUsa`. Users select an attribute—race, gender, threat level, or others—to color-code points with `d3.scaleOrdinal` and view a corresponding bar chart built with `d3.scaleBand`. Hovering over the legend filters the map to highlight one category while fading others, with React managing the dropdown and state.
