A choropleth-style scatterplot maps the geographic distribution of violent crime across U.S. states, using a circle for each crime incident. The visualization relies on vega-lite-api to construct the specification, which is registered with Vega and Vega-Lite, while a custom tooltip handler from vega-tooltip displays the department name on hover. Data is loaded from a GitHub-hosted CSV, with a filter excluding certain states and a calculated field for zip-code prefixes. The Albers USA projection and a color scale generated with d3’s range and hcl functions map coordinates and hue by crime count.

Total Crimes Map

This map visualizes the total violent crime rates across U.S. metro areas from 1975 to 2015, with each city represented by a semi-transparent circle positioned by latitude and longitude. The visualization layers a geographic outline of U.S. states over the data points, using a color encoding to differentiate crime rates and years. Built with Vega-Lite and rendered through the vega-lite-api, the map employs an Albers USA projection and fetches crime data from a CSV file, while state boundaries come from a TopoJSON source. The tooltip feature provides detailed city information on hover.

Total Crimes Map

This visualization displays the total number of crimes across U.S. cities using a choropleth map layered with circular points. The map renders U.S. states as geographic shapes and overlays city-level crime totals as circles, colored by value and showing city names on hover. It is built with Vega-Lite and the Vega-Lite API, using the `vl.markGeoshape` and `vl.markCircle` layers, an Albers USA projection, and TopoJSON data for state boundaries. Crime data originates from the U.S. Metro Areas Violent Crime Rates dataset, loaded via D3’s `csv` parser.

A choropleth of the United States visualizes violent crime rates per state from 1999 to 2019. The map uses SVG circles positioned via `d3.geoAlbersUsa` and `d3.geoPath` to represent state-level crime counts, with circle size and color encoded through `d3.scaleLinear`. Users select a year and crime type (e.g., homicide, robbery) from dropdown menus, triggering a redraw of the map with updated data. The visualization loads state geometries from `us-states.json` and coordinates from `states_lon_lat.json`, with data from the `estimated_crimes_1999_2019.csv` file.

Untitled

This interactive map visualizes violent crime rates across U.S. states from 1999 to 2019, with dropdown menus to select the year and crime type. Circles sized and colored by bivariate linear scales (d3.scaleLinear) are overlaid on a U.S. map projected using d3.geoAlbersUsa with d3.geoPath. The visualization uses d3.json to load state boundaries and coordinates, with hover tooltips showing state names and values.

Untitled

An interactive choropleth map displays property crime rates across U.S. states from 2009 to 2019, with dropdown menus to select the year and crime type (property crime, burglary, larceny, or motor vehicle theft). The map uses `d3.geoAlbersUsa` projection and `d3.geoPath` to render state boundaries from a TopoJSON file. Crime values are mapped to a red color scale using `d3.scaleThreshold`, with a legend generated via `d3.legendColor`. Hovering over a state reveals a tooltip with details, and the visualization updates dynamically through SVG transitions.

Untitled

This visualization plots U.S. state-level crime statistics, showing violent crime totals against homicide cases for each state, with bubble size encoding population and color assigned by state name. The chart uses d3.v4 with d3-scale-chromatic for color mapping and includes an interactive tooltip that displays the state name on hover, while also fading out non-hovered bubbles. Data comes from the estimated_crimes.csv file, rendered as SVG circles with axes and labels generated using d3.axisBottom and d3.axisLeft.

Working Tooltips

This example displays a map of U.S. zip code locations as colored dots, with each color corresponding to the first two digits of the zip code. Hovering over a dot reveals a tooltip showing the state name. The visualization uses the Vega-Lite API to define the circle marks, projection, and encoding, while the vega-tooltip library handles the interactive tooltips. Data comes from the vega-datasets zipcodes.csv file, filtered to exclude non-continental states.

ICE 8-1.2

This choropleth map displays the crime rate per 100,000 people across U.S. states, using a sequential blue color scale where darker shades indicate higher rates. Hovering over a state reveals a tooltip with the exact value, while states without matching data appear gray. The visualization loads CSV data and U.S. TopoJSON boundaries, then renders them as SVG paths via `d3.geoPath` with an Albers USA projection. It uses D3 v7 for data binding, color encoding, and interactive tooltips, with state names normalized and matched against FIPS codes for labeling.
