This example shows a multi-series line chart of cumulative COVID-19 deaths per country over time. A Voronoi overlay, built with `d3.Delaunay` and `d3.voronoi`, captures mouse hover events across the SVG, highlighting the nearest data point and its corresponding country line. The chart uses a logarithmic Y-axis and a time-scaled X-axis, with a tooltip labeling the active country, death count, and date. Data comes from the CSSE COVID-19 global time-series dataset, rendered using React and D3 v7.

Voronoi Overlay with Labels

A multi-line chart displays cumulative COVID-19 deaths over time for multiple countries, with a logarithmic y-axis. A Voronoi overlay, built with `d3.Delaunay`, captures mouse hover events across the chart area, highlighting the nearest data point and its corresponding line. A tooltip with country name, death count, and date follows the cursor, while the active series is emphasized. Data comes from the CSSE COVID-19 time series, rendered as SVG in React using d3 scales and axes.

Voronoi Overlay with Labels

A multi-line chart displays cumulative COVID-19 deaths over time for multiple countries, using a logarithmic y-axis. On hover, a Voronoi overlay from `d3.Delaunay` highlights the nearest data point and activates the corresponding country’s line, displaying a tooltip with the country name, death count, and date. The visualization is built in React with d3 scales, line generators, and axes, rendering to SVG. Data comes from the CSSE COVID-19 time series.

Voronoi Overlay With Labels

This example displays cumulative global COVID-19 deaths over time for multiple countries using a log-scaled line chart. Hovering over any line reveals a tooltip with the country name, death count, and date, while the active line is highlighted. The chart uses React with d3.v5’s `scaleTime`, `scaleLog`, and `line` generators, and implements a Voronoi overlay via `d3.Delaunay.from` and `voronoi.renderCell` to capture mouse events across the SVG. Data comes from the CSSE COVID-19 global time-series dataset, loaded with `d3.csv`.

Voronoi Overlay with Labels

A multi-line chart tracks cumulative COVID-19 deaths over time for multiple countries, with a logarithmic y-axis and interactive hovering. A Voronoi overlay computed with `d3.Delaunay` divides the chart into cells that trigger hover events, highlighting the nearest date’s data point and displaying a tooltip with the country name, death total, and date. The tooltip is rendered as SVG text, and the active country’s line is emphasized. Data comes from the CSSE COVID-19 time series, parsed via `d3.csv` and `timeParse`.

Voronoi with labels

An interactive line chart displays cumulative COVID-19 death counts over time for multiple countries, using a logarithmic y-axis. A Voronoi overlay, built with `d3.Delaunay` and `d3.delaunay.voronoi`, captures mouse hover events across the entire chart area, highlighting the nearest data point and its corresponding country line while displaying a tooltip with the country name, date, and death total. The visualization uses React state for active selection, SVG for rendering, and data sourced from the CSSE COVID-19 time series dataset.

Voronoi Overlay with Labels

This example visualizes cumulative COVID-19 death counts over time for multiple countries using a line chart with a logarithmic y-axis. It renders the paths in SVG and overlays a Voronoi diagram created with `d3.Delaunay` to enable precise mouse hovering on any line segment, highlighting the corresponding country’s path and displaying a tooltip with the country name, death total, and date. Data comes from a CSV file of global time-series deaths, processed with `csv` and `timeParse`. Interactions are managed via React state, while axes are drawn with `axisBottom` and `axisLeft`.

Voronoi Overlay with Labels

This chart displays cumulative COVID-19 death counts over time for multiple countries, with a logarithmic y-axis. A Voronoi overlay (computed via `d3.Delaunay.from` and `voronoi.renderCell`) enables hover detection on any data point, highlighting the corresponding country's line and showing a tooltip with the exact date, death count, and country name. The SVG renders reactively, using `d3.scaleLog`, `d3.scaleTime`, and the `d3.line` generator, with data from the CSSE COVID-19 time series.

Voronoi Overlay with Labels

This example displays global COVID-19 cumulative death totals over time as multiple line charts, one per country, on a logarithmic y-axis. Hovering over any point highlights that country’s entire line and shows a tooltip with the country name, death count, and date. The interactive hover detection uses a Voronoi overlay generated from the data points via `d3.Delaunay` and `d3.voronoi`, mapping mouse events to the nearest point. The line chart is built with React and rendered as SVG, using `d3.scaleTime`, `d3.scaleLog`, and `d3.line`, with data sourced from the CSSEGISandData COVID-19 time series CSV.
