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`.

AI-generated description

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 by Country over Time (with Voronoi Hover)

This interactive line chart displays cumulative COVID-19 deaths by country over time, using a logarithmic y-axis. Hovering over any data point triggers a Voronoi overlay (built with `d3.Delaunay`) to highlight the nearest country’s entire time series and show a tooltip with the exact date and death count. The visualization is rendered as SVG in React, with axes and scales from d3.v5, and pulls data from the Johns Hopkins Coronavirus dataset.

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 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.

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

This visualization shows cumulative coronavirus deaths over time for each country, using a log-scaled y-axis to accommodate wide disparities in death counts. Hovering over any point highlights the corresponding country’s line in black and displays a tooltip with the country name, death total, and date. The interactivity is powered by a Voronoi overlay built with `d3.Delaunay`, which assigns each data point a cell that captures nearby mouse events. The chart is rendered with React and SVG, with axes and scales from d3, and pulls data from the Johns Hopkins COVID-19 dataset.

Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

A fork of a line chart showing cumulative COVID-19 deaths over time for multiple countries, plotted with a logarithmic y-axis. Hovering over the chart highlights a country’s full time series in bold black, using a Voronoi overlay built with `d3.Delaunay` to capture mouse events on the densely overlapping lines. The visualization is rendered as SVG via React, with data sourced from the Johns Hopkins Coronavirus dataset, and uses `scaleLog`, `scaleTime`, and D3’s `line` generator to position and draw each country’s path.

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

This interactive line chart displays cumulative coronavirus deaths by country over time, using a logarithmic scale to compare countries with vastly different death tolls. Hovering over the visualization triggers a Voronoi overlay, built with d3-delaunay, to identify the nearest data point and highlight its corresponding line with a tooltip. The chart is rendered with SVG within a React framework, using d3.scaleTime and d3.scaleLog for axes and d3.line for path generation. Data comes from the Johns Hopkins Coronavirus Dataset.

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

This chart shows cumulative COVID-19 deaths over time for each country, plotted on a log-scaled y-axis. Hovering over any point highlights that country’s full line and displays a tooltip with the exact death count and date. The visualization uses React with D3 v5 scales (`scaleTime`, `scaleLog`) and line generators, while `d3.Delaunay` from `d3-delaunay` builds a Voronoi overlay to capture mouse events, making it easy to select nearby data points. Data comes from the Johns Hopkins Coronavirus dataset via CSV.
