Finished 2016

A choropleth map of the United States shows the total number of West Nile virus cases per million people for 2016, with a logarithmic color scale ranging from white to green. State polygons are rendered using the Albers USA projection via `d3.geo.path` and `d3.geo.albersUsa`, with data loaded from a CSV file using `d3.csv`. Hovering over a state triggers a tooltip displaying the state name and its case count, implemented through D3 mouse events and a styled HTML div. The visualization is built with D3 version 3 and SVG.

Finished 2015

A choropleth map shows West Nile Virus cases per million people across US states for 2015, using a logarithmic color scale ranging from white to green to indicate case intensity. The visualization, built with D3 version 3, uses the Albers USA projection to render state boundaries as SVG paths from GeoJSON data. Interactive tooltips display the state name and case total on mouseover, with the underlying data loaded from a CSV file containing state-level case counts.

2015

A choropleth map of the United States displays West Nile virus case rates per million people for 2015, with states colored on a logarithmic green scale. The visualization uses D3 v3 with an Albers USA projection and SVG paths drawn via `d3.geo.path`. State data from a CSV file is joined to GeoJSON features, and interactive tooltips reveal exact values on hover, with a legend and title provided in the HTML.

Virus chloropleth

This visualization presents a choropleth map of the United States, displaying the total number of West Nile virus cases per state for 2015. Each state's fill color corresponds to the case count, with a logarithmic color scale ranging from white to green. Hovering over a state reveals a tooltip showing the state's name and its specific case total. The map is rendered using D3 v3 with an Albers USA projection (`d3.geo.albersUsa`), geographic paths from GeoJSON, and is styled with CSS.

Virus chloropleth

This visualization displays the total Zika virus cases per U.S. state in 2016 using a choropleth map. The map uses a logarithmic color scale from white to green, with state boundaries drawn as SVG paths via D3’s `d3.geo.path` and the Albers USA projection. Tooltips reveal state names and case counts on mouseover. The code loads data from CSV files and merges it with GeoJSON state outlines, building on examples by Michelle Chandra and Scott Murray.
