This choropleth map visualizes the distribution of total earthquakes across U.S. states, using a logarithmic color scale based on d3.scaleThreshold and the d3.schemeOrRd sequential color scheme. It renders each state as an SVG path via d3.geoPath with a d3.geoAlbersUsa projection, pulling geographic boundaries from TopoJSON and earthquake counts from a CSV. Hovering highlights states with a red stroke, while a d3-tip tooltip is intended to display state name, region, and earthquake count.

Earthquake Choropleth Map

This choropleth map visualizes the total number of earthquakes for each U.S. state, using a logarithmic color scale to differentiate magnitudes. The map renders state boundaries from a TopoJSON file, and the color of each state is determined by its earthquake count, with a threshold-based color scale (`d3.scaleThreshold`) and a sequential color scheme (`d3.schemeOrRd`). The visualization uses D3 v5's geographic projection (`d3.geoAlbersUsa`) and `d3.geoPath` for drawing, while an interactive tooltip (`d3.tip`) displays the state name, region, and exact earthquake count on hover, with data sourced from a CSV file.

Earthquake Choropleth Map

This choropleth map visualizes earthquake totals across U.S. states, using color intensity to show logarithmic counts in a sequential red scheme. The map renders geographic boundaries with `d3.geoPath` and the Albers USA projection, while state colors are assigned via a `d3.scaleThreshold` using `d3.schemeOrRd`. Data comes from a CSV of earthquake records and TopoJSON state geometries, processed using the `topojson.feature` API. Hovering a state highlights its border through CSS, though tooltip code is incomplete in the source.

Earthquake Choropleth Map

The Earthquake Choropleth Map visualizes the total number of earthquakes per U.S. state from 2010 to 2015, using a logarithmic color scale applied via `d3.scaleThreshold` and `d3.schemeOrRd`. The map renders U.S. states as SVG paths with `d3.geoPath` and an AlbersUSA projection, built from TopoJSON data. Hovering triggers a custom tooltip that displays state, region, and earthquake count, styled through CSS. The visualization uses D3 v5 to load CSV data and TopoJSON geometry.

Earthquake Choropleth Map

A choropleth map of the United States visualizes the logarithmic count of total earthquakes by state, with counties colored using a threshold-based scale from the d3.schemeOrRd sequential color scheme. The map is rendered as an SVG, with each state drawn via the d3.geoPath projection. Hovering over a state triggers a tooltip, implemented with a custom d3.tip, that displays the state name, region, and earthquake count. The geographic boundaries and earthquake data are loaded from TopoJSON and CSV files, respectively.

Earthquake Choropleth Map

This choropleth map visualizes earthquake counts across U.S. states using a logarithmic color scale from the OrRd scheme. It shows total earthquakes per state, with darker shades representing higher counts and hover effects highlighting individual states. The visualization uses D3 v5 with d3.geoAlbersUsa projection and d3.geoPath to render TopoJSON state boundaries from the states-10m dataset. State earthquake data comes from a CSV file, and a custom tooltip displays state name, region, and earthquake count on hover.

Earthquake Choropleth Map

This choropleth map visualizes the number of earthquakes recorded in U.S. states, using a logarithmic color scale to represent data from a CSV dataset of state earthquake counts. The map renders U.S. state boundaries via `d3.geoPath` with a `d3.geoAlbersUsa` projection, using TopoJSON data for the geographic shapes and `d3.scaleThreshold` with the `d3.schemeOrRd` color scheme. Hover interactions are implemented through a d3-tip tooltip, while state styling changes on mouseover through CSS-based `:hover` rules.
