Fork of Working Zoom/Pan

Working Zoom/Pan

A choropleth-style stacked bar chart displays Colorado county voting results from a local CSV dataset, with each bar split into yes and no votes. Users can interactively zoom and pan across the chart using D3's zoom behavior, which updates the SVG visualization in real time. The chart uses d3.stack to create layered bars, d3.scaleBand for county positioning, and d3.scaleLinear for vote counts. Tooltips appear on hover, showing county names and vote tallies loaded from the external CSV file.

Working Zoom/Pan

This visualization displays Colorado county voting data for a ballot proposition, showing stacked bars of yes and no votes for each county. The chart uses D3 v4’s `d3.zoom` and `d3.event.transform` with `rescaleX` to enable panning and zooming along the horizontal axis, while vertical movement is locked. Hovering over bars or counties reveals a tooltip with county-specific vote counts, using the `tooltip` module from `svgGlobals.js`. Data originates from a GeoJSON file of Colorado counties and a CSV of proposition results, rendered as SVG.

Fork of Fork of Fork of colorado county data bar chart zoom

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.

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 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 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.
