This example visualizes cumulative coronavirus deaths over time for multiple countries using a log-scaled line chart. A Voronoi overlay, generated with `d3.Delaunay` and `d3.voronoi`, makes each line segment hoverable, highlighting the active country’s path in black. The chart uses `scaleTime` and `scaleLog` for axes, with data from the CSSE COVID-19 time series. React manages the hover state, while SVG renders the paths and overlay.

Coronavirus Deaths Over Time by Country With Voronoi Overlay

This interactive line chart displays cumulative coronavirus deaths over time for multiple countries using a log-scaled y-axis. A Voronoi overlay, built with `d3.Delaunay` and `d3.voronoi`, captures mouse hover events on any point along a country’s trajectory, highlighting that country’s full line in black. The chart renders SVG paths via React, with axes generated by D3’s `axisBottom` and `axisLeft`. Data comes from the Johns Hopkins COVID-19 time-series dataset.

Coronavirus Deaths Over Time by Country With Voronoi Overlay

This example displays cumulative COVID-19 deaths over time for multiple countries as a multi-series line chart using a log scale. A Voronoi overlay facilitates mouse interaction by partitioning the chart into regions nearest each data point. The visualization is built with React and D3 v5, using d3-scale for axes and d3-delaunay for the Voronoi diagram. Data comes from the Johns Hopkins Coronavirus dataset, rendered as SVG paths with hover events logging interactions.

Coronavirus Deaths by Country over Time (with Voronoi Hover)

This example displays cumulative COVID-19 deaths per country over time using a log-scaled line chart. A Voronoi overlay, constructed with `d3.Delaunay`, enables precise hover detection across all data points, highlighting the nearest country’s line and displaying a tooltip with the death count, country name, and date. The chart uses `d3.scaleTime`, `d3.scaleLog`, and `d3.line` with React for rendering, pulling timeseries data from the Johns Hopkins COVID-19 dataset.

Coronavirus Deaths Over Time by Country with Voronoi Overlay

A multi-line chart displays cumulative COVID-19 death totals over time for each country, using a logarithmic y-axis to accommodate disparate magnitudes. A Voronoi overlay, computed with `d3.Delaunay`, maps the nearest data point to mouse coordinates, so hovering highlights that country's trajectory in black. The visualization uses React, D3 v5's `scaleTime` and `scaleLog`, and renders SVG paths from the Johns Hopkins CSSE dataset.

Coronavirus Deaths Over Time by Country With Voronoi Overlay

This graphic displays cumulative COVID-19 death counts per country on a logarithmic scale, with each country’s trajectory drawn as a line over time. A Voronoi overlay using `d3.Delaunay` enables interactive highlighting: hovering over any cell activates the corresponding country’s line, which thickens and turns black. Built with React and rendered as SVG, the chart uses `d3.scaleLog`, `d3.scaleTime`, and `d3.line` to map data from the Johns Hopkins Coronavirus Dataset.

Coronavirus Deaths Over Time by Country With Voronoi Overlay and tooltips

This line chart shows cumulative coronavirus deaths over time for countries with more than 1,000 total deaths, using a log scale for the y-axis. A Voronoi overlay, built with `d3.Delaunay`, enables hover detection on the dense line chart, highlighting the active country’s path in black. The visualization uses React with `d3.scaleTime`, `d3.scaleLog`, and `d3.line`, rendering SVG elements with axes from `d3.axisBottom` and `d3.axisLeft`. Data comes from the Johns Hopkins Coronavirus Dataset and is loaded via `d3.csv`.

Coronavirus Deaths Over Time by Country with Voronoi Overlay

This visualization displays cumulative coronavirus death totals over time for multiple countries, with a Voronoi overlay that enables smooth hover interactions to highlight individual country lines. The chart uses a logarithmic y-axis to accommodate the wide range of death counts, while gray lines represent all countries and a black line marks the actively hovered one. Built with React and D3 v7, it employs d3-delaunay’s Voronoi diagram to compute pointer proximity, with data sourced from the CSSEGISandData COVID-19 global time series.

Coronavirus Deaths Over Time by Country With Voronoi Overlay

This line chart shows cumulative COVID-19 deaths over time for multiple countries, with the most recently hovered country’s line highlighted in black. A Voronoi overlay, built with `d3.Delaunay` and `d3.voronoi`, simplifies mouse interaction by assigning each data point a cell that triggers the highlight. The chart uses `d3.scaleTime` for the x-axis, `d3.scaleLog` for the y-axis, and renders paths via `d3.line`. Data comes from the CSSEGISandData COVID-19 time series CSV, parsed with `d3.csv` and `d3.timeParse`.
