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 by Country over Time (with Voronoi Hover)

A multi-line chart tracks cumulative COVID-19 deaths over time for each country, using a logarithmic y-axis to accommodate wide numeric ranges. Hovering over any point triggers a Voronoi overlay, powered by `d3.Delaunay`, to highlight the nearest country’s full trajectory and display a tooltip with its death count and date. The visualization is built with React and D3 v5, rendering SVG paths via `d3.line` and scales from `d3.scaleTime` and `d3.scaleLog`. Data comes from the Johns Hopkins Coronavirus dataset.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

This chart displays cumulative COVID-19 deaths over time for each country, plotted on a logarithmic y-axis. The visualization features semi-transparent Voronoi cells overlaid on the line chart, enabling hover interactions that highlight the closest data point to the cursor, emphasizing the active country’s line in black. Built with React and D3 v5, it uses `d3.scaleTime`, `d3.scaleLog`, `d3.line`, and `d3.Delaunay` for the Voronoi overlay. Data comes from the Johns Hopkins Coronavirus Dataset, rendered as an SVG.

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 Over Time by Country With Voronoi Overlay

A multi-line chart tracks cumulative COVID-19 deaths over time for each country using a log-scale y-axis, sourced from the Johns Hopkins Coronavirus Dataset. Hovering over any point via a d3-delaunay Voronoi overlay highlights that country’s full timeseries in red, while all other lines remain muted. The SVG is built with React, using d3.scaleTime, d3.scaleLog, and d3.line for rendering.

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`.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

This chart displays cumulative COVID-19 deaths over time for each country as thin gray lines on a logarithmic y-axis, using data from the Johns Hopkins Coronavirus Dataset. A Voronoi overlay, computed with `d3.Delaunay` from the d3-delaunay library, renders red cells over three hardcoded points, providing a potential interaction region for hover events. The React-based visualization employs `d3.scaleLog`, `d3.line`, and `d3.axisBottom`/`d3.axisLeft` to construct the SVG, with axis tick marks drawn as grid lines.

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

This chart tracks cumulative COVID-19 deaths by country over time on a logarithmic scale, using data from the Johns Hopkins Coronavirus Dataset. Each grey line represents a country’s death trajectory, and hovering over a data point via a Voronoi overlay highlights the corresponding country’s full series in black while displaying a tooltip with the exact date and death count. The visualization is built with React and D3 v5, employing `d3.scaleLog`, `d3.line`, and `d3.Delaunay` from the d3-delaunay library to enable smooth hover interactions across the SVG-rendered paths.

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

A multi-line chart tracks cumulative COVID-19 deaths over time for each country, using a log scale to accommodate wide value ranges. Hovering over any point triggers a Voronoi overlay, built with `d3.Delaunay`, to highlight the nearest data point, illuminate that country’s line, and display a tooltip with the death count and date. The visualization uses React and d3.v5, rendering SVG elements and pulling data from the Johns Hopkins Coronavirus dataset.
