This visualization shows recent earthquake activity in Oklahoma, with each quake plotted as a crimson circle sized and colored by magnitude against a map of the state and its counties. The map uses a tile-less D3 v4 approach with `d3.geoAlbersUsa` projection and `d3.geoPath` to render TopoJSON boundaries. Earthquake data comes from the USGS live feed, filtered to visible points, with a categorical color scale for magnitude ranges and a legend showing counts per magnitude bin. A mouse-move handler displays geographic coordinates.

This example shows a map of Oklahoma with earthquake locations plotted as semi-transparent crimson points, sized by their position on the map. The visualization filters earthquake data to only include events with a magnitude of 2.5 or greater. It uses d3 v4's `d3.geoAlbersUsa` projection and `d3.geoPath` to render SVG paths for state and county boundaries, sourced from TopoJSON data, while earthquake data comes from the USGS feed.

Class 5

This visualization displays earthquakes from the past week across a map of the United States, with points colored by magnitude and a legend showing the number of quakes in each magnitude range. It uses d3.geoPath with a d3.geoAlbersUsa projection to render TopoJSON state boundaries, while earthquake data arrives as GeoJSON from the USGS feed. The map includes a draggable orange circle, and mouse movement updates a readout of geographic coordinates using the inverse projection.

Class 5

This map of the United States displays earthquake locations from the USGS live feed for the past week, with each quake represented as a circle colored by magnitude using a D3 ordinal color scale. The visualization uses `d3.geoAlbersUsa` for the map projection, `d3.geoPath` to render state boundaries, and `topojson.v2` for GeoJSON conversion. A legend at the right shows magnitude ranges with quake counts, while mouseover coordinates are displayed via a D3 text element.

Class 5

This visualization displays earthquake locations across the United States from the USGS live feed, with each quake colored by magnitude using a d3.scaleOrdinal color scale. State boundaries render as gray paths via TopoJSON and d3.geoPath with an AlbersUSA projection. A legend with circles shows magnitude ranges and counts, while hovering reveals coordinates through d3.mouse and projection.invert. The map filters quakes to viewport-visible coordinates and removes legend entries exceeding the largest observed magnitude.

class-07 demo

This visualization displays a week of earthquake data overlaid on a map of Oklahoma, using a tile-based OpenStreetMap basemap for geographic context. It plots earthquake epicenters as crimson paths, filtering out events below a 2.5 magnitude threshold. The map uses a Web Mercator projection via `d3.geoMercator` and renders geographic features with `d3.geoPath`, including state and county boundaries from TopoJSON files. The basemap is composed of image tiles fetched from the OpenStreetMap tile server using the `d3.tile` API. Earthquake data is sourced from a local GeoJSON file rather than the live USGS feed.

A map of Oklahoma displays earthquake epicenters as red points on a blank state background, with county borders outlined in gray. The visualization filters earthquake records by a magnitude threshold and projects them using `d3.geoAlbersUsa`. The code loads GeoJSON and TopoJSON data via `d3.json` and renders the geographic features with `d3.geoPath`.

This example plots earthquake data from the USGS feed as filled paths on a map of Oklahoma, using county and state boundary shapes from a TopoJSON file. The visualization uses an Albers USA projection via `d3.geoPath` to render both the geographic outlines and the quake features, with a threshold magnitude of 2.5 filtering the displayed events. Earthquakes appear as crimson semi-transparent shapes, while the map layer is drawn separately in a background group. The code also logs earthquake counts for California and the earliest event time to the console.

Class 5 v2

This map shows the United States with earthquakes from the USGS all-week feed marked as crimson points. A legend categorizes earthquake magnitudes into six bins, with each point’s color assigned by its magnitude. The visualization uses d3.geoAlbersUsa and d3.geoPath to project and draw state and quake paths, while a custom d3.legend plugin renders the color scale. State boundaries and quake locations are plotted via topojson.v2 and d3.json, with a mouse-tracking coordinate readout using projection.invert.
