This example displays a map of US states rendered in gray with an Albers USA projection, overlaid with crimson points marking earthquake locations from the USGS live GeoJSON feed. It uses d3.geoPath for both state boundaries and earthquake points, with topojson to convert US state geometries. As the mouse moves over the map, a text display updates to show the geographic longitude and latitude in degrees, computed via projection.invert and d3.mouse. The visualization layers states and earthquakes in separate SVG groups, with a fixed SVG canvas sized 960 by 500 pixels.

class 3 - states

This example displays a map of the United States with earthquake locations overlaid as crimson points. The map is rendered using SVG paths created with `d3.geoPath` and a `d3.geoAlbersUsa` projection, while earthquake data is loaded from the USGS GeoJSON feed and plotted with the same path generator. The visualization also shows the latitude and longitude of the mouse cursor in a separate text element, using the projection’s `invert` method to translate screen coordinates to geographic coordinates.

This visualization shows a map of the United States with earthquake locations overlaid, using a dark gray state outline on a blue background. It loads US state boundaries from a remote TopoJSON file and renders them with `d3.geoPath` using the `d3.geoAlbersUsa` projection. Earthquake data is fetched from the USGS GeoJSON feed and plotted as crimson circles. A mouse-move handler displays the current latitude and longitude in a separate text layer.

A U.S. map displays all 50 states in gray with a blue background, overlaid with red circles marking earthquake locations from the USGS live feed. The visualization plots both state boundaries and seismic events using d3.geoPath with the d3.geoAlbersUsa projection, filtering earthquake data by magnitude into four color-coded legend categories. The code loads TopoJSON state data and GeoJSON earthquake data via d3.json, with a legend showing magnitude ranges from 1.0 to 4.0+.

class 3 - states

This example shows a map of the United States with earthquakes from the past week overlaid as colored points. The map uses an Albers USA projection with state boundaries rendered via `d3.geoPath` and TopoJSON data from the UMBC visualization course. Earthquake locations come from the USGS GeoJSON feed, with points colored by magnitude using a scale from green to red. A legend in the corner explains the magnitude ranges, while a mousemove event displays latitude and longitude coordinates using `projection.invert`.

This example displays a map of the United States overlaid with earthquake locations from the USGS’s daily GeoJSON feed. The visualization shows each earthquake as a small path marker on top of the state boundaries. The map uses the `d3.geoAlbersUsa` projection and `d3.geoPath` to render the geographic shapes, with state outlines drawn from TopoJSON data. Earthquake points are appended as `path` elements with a crimson fill, while the states are styled in a light yellow, highlighting the spatial distribution of recent seismic activity.

class 4 - states

This example displays a map of the contiguous United States with earthquake locations overlaid as crimson points. The map is rendered using `d3.geoPath` with the `d3.geoAlbersUsa()` projection, while earthquake data is pulled from the USGS live GeoJSON feed. State boundaries come from a local US GeoJSON file processed with `topojson.feature`. The visualization also includes a static legend and interactive coordinate display, which updates as the mouse moves across the map. All drawing is performed with SVG elements.

class 5 - states

This example displays a map of United States state boundaries rendered in SVG using d3.geoPath with the d3.geoAlbersUsa projection. It overlays earthquake locations from the USGS live GeoJSON feed, with earthquakes plotted as crimson paths on the map. The code uses topojson to convert state topology data and d3.json to load both the state boundaries and earthquake data. A legend is included, and the visualization also shows a coordinate readout that updates on mousemove events, revealing the current latitude and longitude under the cursor.
