This visualization combines OpenStreetMap raster tiles with vector data for Oklahoma using d3-tile and d3.geoPath with a Mercator projection. It overlays county boundaries from a TopoJSON file, drawn as black lines, alongside earthquake points from a USGS GeoJSON feed, rendered as semi-transparent crimson circles. The quakes are filtered by magnitude threshold, and the tile layer uses the d3.tile layout to compute visible tiles. Both the raster images and vector shapes are rendered as SVG elements.

AI-generated description

Using d3-tile to display raster image tiles underneath some TopoJSON vectors. Compare to the zoomable version.

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 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.

Raster & Vector I

This example overlays OpenStreetMap raster tiles with vector map data for Oklahoma counties. It uses d3-tile to fetch and position the image tiles, while d3.geoPath projects and draws the TopoJSON county boundaries. The map is rendered as SVG, with the vector geometries styled in gray and the tile images providing geographic context. The code also includes an unused quake styling class.

This example shows earthquake activity in Oklahoma on a map. The map is rendered with OpenStreetMap tiles and a vector overlay of state borders. The code uses the `d3.geoMercator` projection, `d3.geoPath`, and `d3.tile` to create the base map. It filters earthquakes from the USGS GeoJSON feed using `d3.geoContains` to show only quakes within Oklahoma. The quakes are drawn as crimson paths, while the street data comes from a TopoJSON source.

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.

Homework 7

This map shows Oklahoma counties overlaid on OpenStreetMap raster tiles, with a crimson semi-transparent point pattern and county mesh outlines. The visualization combines tiled map imagery via `d3.tile` with geographic county boundaries from a TopoJSON file, projected using `d3.geoMercator` and rendered as SVG paths through `d3.geoPath`. Quake data appears as filled circles, though no dataset is explicitly loaded here. The code uses D3 v4, TopoJSON, and the `d3-tile` plugin to compose the interactive layout.

March 30 class

This map shows the state of Oklahoma with a street overlay, rendered atop OpenStreetMap tiles. Red dots mark earthquake epicenters from the USGS all-week feed that fall within the state’s boundaries. The visualization uses a D3 Mercator projection fitted to the Oklahoma geometry, and fetches tile images and GeoJSON data via `d3.json`. The code employs `d3.geoPath`, `d3.geoContains`, and `topojson.mesh` to draw the state boundary and filter earthquakes.
