This example visualizes Colorado county election data, showing a bar chart that zooms into geographic regions. When users hover over an individual county, a tooltip displays the number of yes and no votes for a specific ballot proposition. The visualization combines a county GeoJSON map with CSV vote data, using d3.select, d3.json, and d3.csv to load and parse the datasets. The map and bars are built with React hooks alongside D3 v7, with margins and SVG sizing defined in the component.

AI-generated description

An example showing the capabilities of VizHub:

  • if you hover over a county it will display the number of yes votes and no votes for the current proposition
  • TODO:
  • -color the map according to the number of votes
  • -add a selector for multiple propositions
  • -clean up code and functions into multiple classes

Fork of Fork of colorado county data bar chart pt 2

This example displays a stacked bar chart of yes and no votes for a Colorado ballot proposition, with one bar per county. Hovering over a county bar currently shows a tooltip, though the tooltip event handlers are commented out, so the feature is inactive. The visualization uses d3.csv and d3.json to load voting data from a CSV and county boundaries from a GeoJSON file, then renders the chart with d3.stack, d3.scaleBand, d3.scaleLinear, and d3.axisBottom. It also implements zoom and pan capabilities using d3.zoom with an invisible overlay rect to capture pointer events.

Fork of Fork of Fork of colorado county data bar chart pt 2

This bar chart visualizes Colorado county voting data for a proposition, with stacked bars showing the number of yes and no votes per county. Hovering over a bar reveals a tooltip displaying the vote counts for that specific county. The visualization uses d3.stack, d3.scaleBand, and d3.scaleLinear to construct the chart, while d3.zoom enables panning and zooming along the x-axis. Vote data comes from a CSV file and county geometry from a GeoJSON source, rendered as SVG via D3 v4.

Fork of Fork of Fork of colorado county data bar chart pt 2

This visualization displays Colorado county election results as a stacked bar chart, with each bar representing the yes and no vote counts for a specific proposition. Hovering over a county reveals a tooltip with the exact vote numbers. The chart uses D3 v4 APIs including `d3.scaleBand`, `d3.scaleLinear`, `d3.stack`, and `d3.zoom` for interactive panning. It loads county boundaries from a GeoJSON file and vote data from a CSV, rendering the bars as SVG rectangles.

Fork of colorado county data bar chart

This fork of a Colorado county bar chart visualizes yes and no votes for a proposition, with each bar representing a county. Hovering over a bar triggers a tooltip that displays the county name along with its yes and no vote counts, using D3’s selection and event handling. The chart uses `d3.scaleBand` and `d3.scaleLinear` for axes, with zoom support via `d3.zoom`. Vote data comes from a CSV file, while county names are sourced from a GeoJSON file for reference.

Fork of Fork of Fork of colorado county data bar chart pt 2

This visualization displays a stacked bar chart of yes and no votes for each Colorado county from a CSV file, rendered using D3.js v4. The chart uses D3’s `scaleBand` and `scaleLinear` functions to map counties and vote counts, with each bar segmented into green and red sections. Hovering over a county triggers a tooltip showing the specific vote tallies. The map data comes from a GeoJSON file, though currently only the bar chart is implemented, not the choropleth.

Fork of Circles with D3

This fork of the D3 circles example creates an interactive bar chart of Colorado ballot measures, displaying yes and no votes per county using stacked bars. It fetches county GeoJSON and vote data from CSV sources, then renders SVG rectangles with D3 scales for position and color. The visualization implements zoomable axes via `d3.zoom` and `rescaleX`, allowing users to pan and magnify the chart. The code uses `d3.json`, `d3.csv`, `select`, and `axisBottom` to manage data loading and rendering.

Fork of Working Zoom/Pan

This example demonstrates a zoomable and pannable stacked bar chart visualizing Colorado county election votes using d3.zoom with scaleExtent and translateExtent to constrain navigation. Data is loaded from external GeoJSON and CSV sources, then rendered using d3.stack, scaleBand, and scaleLinear. The implementation includes SVG clip paths, axis elements, and a tooltip module (svgGlobals.js) for showing vote details—though tooltip interactivity appears commented out in the main rendering code.
