Smoothed Daily Coronavirus Cases Line Chart

Smoothed Daily Coronavirus Deaths Line Chart

This chart plots smoothed daily coronavirus deaths over time for the top 50 countries by cumulative deaths, using a logarithmic y-axis to reveal relative trends across widely varying scales. The React app renders SVG lines with D3 scales and generators, while a D3-Delaunay Voronoi overlay enables hover interaction, highlighting the nearest data point and its corresponding country line with a tooltip. Data comes from the Johns Hopkins COVID-19 dataset, and daily values are smoothed via repeated averaging (15 iterations) before plotting.

Smoothed Daily Coronavirus Deaths Line Chart

A smoothed multi-line chart compares daily COVID-19 deaths over time for the top 50 countries by cumulative deaths. The y-axis uses a logarithmic scale to accommodate wide value ranges, and the lines are smoothed via a repeated averaging technique. Built with React and D3 v5, the visualization uses a Voronoi overlay for hover detection to highlight a selected country's line and display a tooltip with details. Data is sourced from the Johns Hopkins Coronavirus dataset.

Smoothed Daily Coronavirus Deaths Line Chart

Smoothed lines trace daily coronavirus deaths over time for the top 50 countries by cumulative deaths, with a logarithmic y-axis. Hovering activates a Voronoi overlay, built with `d3.Delaunay`, to highlight the nearest data point’s country line and display a tooltip with the exact date and death count. Lines are smoothed via repeated averaging in the `blur` helper, and the visualization renders as SVG using React, D3 v5 scales (`scaleTime`, `scaleLog`), and axes from `d3.axisBottom` and `d3.axisLeft`. Data comes from the Johns Hopkins CSSE GitHub repository.

Smoothed Daily Coronavirus Deaths Line Chart

This chart shows smoothed daily coronavirus death counts over time for the top 50 countries by cumulative deaths, using a logarithmic y-axis to accommodate wide variations in scale. Hovering over any point highlights the entire country’s trajectory and displays a tooltip with the exact date and death total. Built with React and D3 v5, the visualization renders as an SVG and uses a Voronoi overlay for efficient hover detection. Data comes from the Johns Hopkins Coronavirus Dataset, with the daily counts smoothed via repeated averaging.

Smoothed Daily Coronavirus Deaths Line Chart

This chart displays smoothed daily coronavirus deaths over time for the top 50 countries by cumulative deaths, using a log-scaled y-axis and a time-scaled x-axis. Each country is represented by a gray line, and hovering over the visualization highlights the nearest country’s line and shows a tooltip with its name, date, and total death count. The example uses React with D3 v5 APIs such as `scaleLog`, `scaleTime`, `line`, and `axisBottom`, plus a Voronoi overlay (`d3.Delaunay`) for hit-testing. Daily death data is smoothed via repeated averaging in a custom `blur` function. Data comes from the Johns Hopkins Coronavirus Dataset.

Smoothed Daily Coronavirus Deaths Line Chart

This chart displays smoothed daily COVID-19 death counts for the top 50 countries by cumulative deaths, with a logarithmic y-axis to accommodate wide variation. Hovering over any data point uses a d3.Delaunay Voronoi overlay to highlight the corresponding country’s full line and show a tooltip with the date and total deaths. The smoothing is applied via a repeated averaging blur function to the raw Johns Hopkins dataset, and the visualization is rendered as an SVG using React and D3 scales, axes, and line generators.

Smoothed Daily Coronavirus Deaths by Country

A line chart tracks smoothed daily COVID-19 death counts by country over time, using a logarithmic y-axis to accommodate wide numerical ranges. Hovering over any point reveals the country name, cumulative death total, and date, while highlighting that country’s entire trajectory in a thicker black stroke. The visualization relies on React for UI state and D3 v5 for scales, axis generation, and a Voronoi overlay (via `d3.Delaunay`) to capture mouse interactions efficiently. Data comes from the Johns Hopkins Coronavirus dataset, and the smoothing is achieved through repeated three-point moving averages defined in a custom `blur` function.
