OpenStreetMap US Board Election 2017 | OpaVote

This interactive visualization animates the ranked-choice voting tabulation for the 2017 OpenStreetMap US Board election. As ballots are processed, candidates are eliminated one by one in real time, with their votes transferring to the next ranked choice. Each candidate is represented by a colored circle, and the animation shows the progressive redistribution of votes until a winner emerges. The visualization uses the single transferable vote (STV) method, and the final tallies for each candidate are displayed.

USA 2012 presidential election with tweaks

This choropleth map of the USA shows the 2012 presidential election results at the county level, with counties colored by the winning candidate and shaded according to margin of victory. Built with D3 v4 and rendered as SVG, the map uses a TopoJSON file of election data (`elpo12p010g.topojson`) that includes vote counts for Obama, Romney, and other candidates, plus the winning candidate and percentage per county. The visualization uses a sequential color scale, with shades of blue for counties won by Obama and red for counties won by Romney, darker shades indicating higher winning percentages. Each county is drawn as a polygon from the TopoJSON geometry, with fill color determined by the `WINNER` and `PCT_WNR` properties. Hovering over a county likely reveals its name and voting statistics. This block is a tweaked version of a prior election map, adjusted for D3 v4 and using an SVG rendering.

USA 2012 presidential election value-by-alpha (d3v3)

This visualization displays the 2012 U.S. presidential election results at county level using a value-by-alpha choropleth map. Each county polygon is colored by its winning candidate—blue for Obama, red for Romney—with opacity encoded to the winner's vote percentage. The map renders in SVG with smooth animated transitions, using D3.js v3 to load the TopoJSON of county-level election returns and project them geographically. The visualization highlights the geographic distribution of vote margins, with more intense colors representing stronger support. Built with Blockbuilder.org, this work is a fork of almccon's original election map and is released under the MIT license.

USA 2012 presidential election (slow AF version)

This block maps the 2012 U.S. presidential election results by county, coloring each polygon based on the winning candidate (Obama or Romney) and shading by margin of victory. The SVG rendering uses a TopoJSON file of county boundaries with embedded vote counts and percentages, and likely animates the choropleth with a slow transition effect — hence the "slow AF version" title. The map emphasizes the geographic distribution of votes, with counties colored by winner and the intensity of the color representing the margin. The data includes per-county vote tallies for Obama, Romney, and others, plus percentage and winner fields, rendered as an interactive SVG visualization. It is built with blockbuilder.org, forked from almccon's original block.# USA 2012 presidential election (slow AF version) An SVG choropleth map of U.S. counties colored by the 2012 presidential election results. Each county polygon is shaded based on the winning candidate (Obama or Romney) and the margin of victory, with darker shades representing larger winning percentages. County-level data includes vote counts, percentages, and winner for the 2012 election. The map displays all U.S. counties as interactive SVG paths, colored by the winning candidate's share of the vote. The title hints at a deliberately slow animation or transition when changing between states or rendering the visualization. The visualization uses TopoJSON data for county boundaries and was built with Blockbuilder.org, forked from almccon's original block. **Rendering:** SVG **Data source:** [gist](https://gist.github.com/almccon/cb30a0f6bdfa2aa5b15f8022b82bc8b1) **Author:** almccon **Visualization Type:** Choropleth map **Code:** <embed src="..."> (or provide link)Here is a concise description for the gallery: --- **USA 2012 Presidential Election (Slow AF Version)** This choropleth map visualizes the 2012 U.S. presidential election results at the county level. Each county is colored by the winning candidate (Obama or Romney), with color intensity reflecting the winner's percentage of the vote. The map is rendered as an SVG using a TopoJSON dataset that includes per-county vote counts and percentages. The "slow AF" title humorously signals that the visualization is a straightforward, unanimated rendering, focusing purely on the geographic distribution of the vote. **Source:** gist · **Author:** almccon · **Rendering:** SVG

US Election Base Map

This interactive map of the United States provides a zoomable base map for exploring election data across states, counties, and congressional districts. Built with D3.js v3 and TopoJSON, it renders geographic boundaries as SVG paths, with users able to toggle between administrative levels using radio buttons. Clicking a feature triggers a smooth zoom animation into the selected region, while a home button resets the view. A tooltip displays additional context on hover. The map uses a clean white background and subtle gray fill for landmasses, with strokes emphasizing boundaries. The implementation demonstrates reusable D3 patterns and geographic projection handling.

USA 2012 presidential election proportional circles (d3v3)

This block visualizes the 2012 U.S. presidential election results by county, using proportional circles overlaid on a map of the United States. The map is rendered with SVG using D3v3, with each county’s circle sized according to total votes cast and colored to indicate whether Obama or Romney won the county, based on the percentage margin. The underlying geometry is loaded from a TopoJSON file containing county-level election data, and the proportional circles provide a quick visual comparison of vote totals and partisan leanings across the country. The visualization is built with Blockbuilder.org, is available under the MIT license, and is a fork of earlier iterations that evolved from bar symbols to proportional circles.

USA 2012 presidential election (d3v3)

This choropleth map visualizes the results of the 2012 U.S. presidential election by county, using SVG rendering. County-level vote data (Obama, Romney, other candidates, and winner) is encoded as colored polygons, with fill colors derived from the winning candidate and margin of victory via a categorical or sequential color scale. The visualization is built with D3v3 and TopoJSON, with the map geometry loaded from a TopoJSON file.

USA 2012 presidential election value-by-alpha

This visualization shows the 2012 U.S. presidential election results at the county level using a value-by-alpha choropleth, where each county’s fill opacity reflects the winning candidate’s margin of victory. Built with D3 v4 and rendered as an SVG animation, the map encodes data from the included TopoJSON file, with counties colored by winner and opacity scaled by vote share. The visualization updates smoothly via animated transitions, making the geographical distribution of Democratic and Republican support easy to compare across the country.
