This choropleth map visualizes the distribution of total earthquakes across US states using a diverging color scale. The map is rendered as an SVG using D3.js and the `geoAlbersUsa` projection, with state boundaries drawn via `geoPath`. Earthquake counts are logarithmically transformed and mapped to a threshold color scale from the `schemeOrRd` palette, while hovering highlights states in light green. The data is loaded from CSV and TopoJSON files, and tooltips display state name, region, and raw earthquake totals.

Choropleth Map

A choropleth map of the United States visualizes total earthquakes per state on a geographic projection, using a color scale that encodes the logarithmic earthquake count. State regions are colored according to their assigned region, with a sequential color scheme from `schemeOrRd`. The map is rendered as SVG paths using `d3.geoPath` with a `geoAlbersUsa` projection, and earthquake data is loaded from a CSV file. Hovering highlights a state in light green with a dark red stroke.

Choropleth Map

This choropleth map visualizes earthquake totals across US states, using a log-transformed color scale to differentiate seismic activity levels. Built with D3 v5 and TopoJSON, it renders state boundaries as SVG paths via d3.geoPath and the geoAlbersUsa projection. A threshold color scale maps logged earthquake counts to a sequential OrRd scheme, while interactive hover effects highlight individual states. The map also includes embedded tooltips showing state name, region, and raw earthquake totals, with data loaded from CSV and TopoJSON sources.

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

This choropleth map visualizes earthquake counts across U.S. states, using the Albers USA projection and a threshold color scale with a sequential orange-red scheme. The map applies logarithmic scaling to earthquake totals to enhance color distinction, with states colored via `d3.scaleThreshold` and `d3.geoPath` for rendering. Data is loaded from a CSV of state earthquake records and a TopoJSON file of U.S. boundaries, processed with `topojson.feature`. Hovering highlights states in red, though the tooltip code is incomplete and non-functional.

Earthquake Choropleth Map

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

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.
