Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

A fork of a line chart of cumulative COVID-19 deaths over time by country, using a log-scaled y-axis, renders the global dataset from the Johns Hopkins Coronavirus GitHub repository. React components build SVG paths for each country’s time series, while a D3 Voronoi overlay (computed via `d3.Delaunay`) captures mouse hover events to highlight the nearest data point’s country line, turning it black and thicker. The chart uses `d3.scaleTime`, `d3.scaleLog`, and `d3.line` to encode the data, with axes from `d3.axisBottom` and `d3.axisLeft`.

Fork of Coronavirus Deaths by Country over Time (with Voronoi Hover)

This fork of a line chart visualizes cumulative coronavirus deaths by country over time, using a log-scaled y-axis to accommodate wide variation in death tolls. Hovering over any point triggers a Voronoi overlay, powered by `d3.Delaunay`, to highlight the nearest data point, illuminate the corresponding country’s line, and display a tooltip with the date, country, and death count. The chart is built with React and D3 v5, rendering SVG paths from the Johns Hopkins COVID-19 dataset, with axes generated via `d3.axisBottom` and `d3.axisLeft`.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

A fork of a line chart displays cumulative COVID-19 deaths over time for each country on a log scale. Semi-transparent red Voronoi cells, generated by `d3.Delaunay` from a sparse set of points, overlay the chart to illustrate a hover-interaction technique, though the hover handler only logs to the console. Built with React and D3 v5, the SVG visualization renders axes, grid lines, and multiple country paths from the Johns Hopkins dataset.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

This visualization displays global coronavirus deaths over time as a log-scale line chart, with each country’s cumulative death count traced as a separate path. A Voronoi overlay, built using `d3.Delaunay`, partitions the chart area into cells that trigger hover events, highlighting the nearest data point’s country line in black. The chart, rendered as an SVG with React and D3 v5, uses `d3.scaleTime` and `d3.scaleLog` for axes, and pulls data from the Johns Hopkins Coronavirus Dataset.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

A multi-line chart tracks cumulative COVID-19 deaths over time for each country, using a logarithmic y-axis to accommodate wide numeric ranges. The visualization encodes country data from the Johns Hopkins Coronavirus Dataset as gray SVG paths, with an active line highlighted in black when a user hovers over a data point. Hover detection is implemented via a Voronoi overlay computed with `d3.Delaunay`, which assigns the nearest data point to the mouse cursor. The chart is built with React and D3 v5, using `d3.scaleTime`, `d3.scaleLog`, and `d3.line` for axes and path generation.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

A fork of a line chart displays global cumulative COVID-19 deaths over time, with each country’s trajectory as a gray line. A Voronoi overlay, computed via the `d3.delaunay` and `d3.Delaunay.voronoi` APIs, makes the nearest data point under the cursor hoverable, highlighting the corresponding country’s line in black. Built with React and D3 v5, the chart uses `d3.scaleTime`, `d3.scaleLog`, and `d3.line` to map dates and log-scaled death totals, rendering as SVG. Data comes from the Johns Hopkins Coronavirus dataset, parsed with `d3.csv`.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

This chart plots cumulative COVID-19 deaths over time for each country, using a logarithmic y-scale to accommodate wide variation in case numbers. A Voronoi overlay, built with d3-delaunay, enables precise hover detection on the dense line chart, highlighting the nearest data point’s country and redrawing its path in bold black. Data comes from the Johns Hopkins Coronavirus dataset, loaded via d3.csv, with rendering in SVG through React and scales from d3.scaleTime and d3.scaleLog.

Fork of Coronavirus Deaths by Country over Time (with Voronoi Hover)

A multi-line chart tracks cumulative COVID-19 deaths per country over time, using a logarithmic y-axis. Hovering over any point uses a Voronoi overlay to highlight that country's line and display a tooltip with the exact date and death count. Built with React and D3 v5, the visualization leverages `d3.Delaunay` for the Voronoi diagram, `scaleLog` and `scaleTime` for axes, and loads data from the Johns Hopkins Coronavirus dataset via `d3.csv`.
