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.

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 Line Chart

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 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 by Country

This interactive line chart displays smoothed daily COVID-19 death counts for each country, plotted over time on a logarithmic scale. Using the D3.js library with a React frontend, it renders an SVG visualization with a Voronoi overlay for hover detection. The chart applies 20 iterations of a blurring algorithm to the daily death data, and highlights the selected country's line with a tooltip showing total deaths. 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.

Daily Coronavirus Deaths by Country

This visualization displays global coronavirus deaths over time by country, with each country represented as a line on a log-scaled y-axis. Hovering over any point triggers a tooltip showing the country name, total deaths, and date, while highlighting that country’s entire line. Built with React and D3 v5, it computes daily death numbers on the fly from cumulative totals in the Johns Hopkins dataset using d3.csv and d3.timeParse. Interaction is handled via a d3.Delaunay-based VoronoiOverlay that maps mouse position to nearest data points, with axes rendered using d3.axisBottom and d3.axisLeft.

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.
