This smoothed line chart tracks daily COVID-19 death counts over time for the top 50 countries, using a log-scaled y-axis and data from the Johns Hopkins Coronavirus Dataset. The chart applies a Gaussian blur to smooth the raw daily values, rendering each country as a line in an SVG. Hovering over any point triggers a Voronoi overlay built with `d3-delaunay`, highlighting the corresponding country's line and displaying a tooltip with the exact date, total deaths, and country name. The visualization uses React with D3 v5 components like `scaleLog`, `scaleTime`, and `axisBottom`.

Smoothed Line Chart

Smoothed line chart comparing daily COVID-19 deaths across multiple countries, displayed on a logarithmic y-axis. The visualization uses a Gaussian kernel blur to smooth noisy daily counts, revealing underlying trends. Built with React and D3 v5, it employs `scaleTime`, `scaleLog`, and a custom `line` generator, with a D3 Delaunay Voronoi overlay for hover interactions. Hovering a point highlights the corresponding country’s full trajectory and displays a tooltip with the date and total death count. Data comes from the Johns Hopkins Coronavirus Dataset.

Smoothed Line Chart

This example shows smoothed daily death counts over time for the top 50 countries, using a log-scaled y-axis. Each country is rendered as a line, and hovering over any data point highlights the corresponding line and displays a tooltip with the country name, date, and total deaths. The data comes from the Johns Hopkins COVID-19 dataset. The visualization uses React with D3 v5 for scaling, line generation, and axis construction, while a Voronoi overlay built with `d3.delaunay` handles hover detection. The smoothing is applied via a Gaussian kernel blur.

Line Chart

A line chart displays smoothed daily COVID-19 death counts over time for the top 50 countries, colored by data from the Johns Hopkins Coronavirus Dataset. It uses a logarithmic y-scale and a Gaussian kernel blur to smooth the time series. Hovering over a Voronoi overlay, generated with `d3.Delaunay`, highlights the nearest data point and illuminates the corresponding country’s line, while a tooltip shows the country, date, and approximate death total. The chart is built with React and D3 v5, rendering SVG paths via `d3.line` and axes with `d3.axisBottom` and `d3.axisLeft`.

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.

Fork of Smoothed Daily Coronavirus Deaths Line Chart

This chart shows smoothed daily COVID-19 death counts for the top 50 countries, with each line representing a country's timeseries over time. Using a logarithmic y-scale, the visualization compares mortality trends across nations, and the Voronoi overlay enables interactive hover to highlight specific countries. The data comes from the Johns Hopkins Coronavirus Dataset, processed through repeated averaging smoothing (blur) to reduce noise. Built with React and D3 v5, the code utilizes d3.scaleTime, d3.scaleLog, d3.line, and d3.Delaunay for the voronoi interaction, rendering as SVG.

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

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

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.
