This line chart visualizes the cumulative and daily COVID-19 case counts for ten countries up to July 28, with buttons to toggle between total and daily cases. Lines are drawn with an animated stroke-dashoffset transition using D3’s `transition()` method, and SVG paths are generated via `d3.line()`. The chart includes a color legend mapping countries to a categorical scheme, axis labels, and annotations marking notable events. Data is loaded from a CSV file, and the visualization is built with React and D3 v5, rendered as SVG with animation.

Line Chart with Multiple Lines

This visualization displays the cumulative COVID-19 case counts for the top 10 countries from January to July 2020, using multiple animated line paths over a time-based x-axis and a linear y-axis. Each country’s line is color-coded via a d3.scaleOrdinal with a category scheme, and a legend is rendered with d3’s select/enter/merge pattern. The lines animate using `transition.attrTween`-like path drawing with `stroke-dasharray` and `stroke-dashoffset`, while axes are built with d3.axisBottom and d3.axisLeft. Data comes from a CSV file, loaded without visible d3.csv (assumed external).

Line Chart of New Covid cases in country of 3 pandemic years (interactive)

This interactive line chart displays new COVID-19 cases across ten countries over a three-year period. The visualization uses progressively fading non-hovered lines and relies on hovering over a country name in the legend to highlight its individual trend. Built with React and D3 v5, the chart employs D3’s `scaleTime` and `scaleLinear` for axes and `line` with `curveNatural` for rendering each country’s SVG path. The underlying data is sourced from a CSV file provided in the repository.

Covid cases with interaction with country

A line chart displays new daily COVID-19 cases for ten countries from a CSV dataset, with each country’s trend as a colored curve. Hovering over a country name in the legend highlights that specific line and fades the others, implemented via React state and `onMouseEnter` handlers. The visualization uses D3 v5 scales (`scaleTime`, `scaleLinear`, `scaleOrdinal`), the `d3.line` generator with `curveNatural`, and custom React components for axes and the interactive legend, rendering to SVG.

Melting Data for Multiple Lines

This example shows animated multi-line charts tracking COVID-19 confirmed cases over time for several countries, with colored lines that progressively extend as the day counter advances. A legend and axis labels accompany the visualization. The code uses d3.nest() to group data by country, d3.line() with curveBasis for smooth paths, and d3.scaleLinear for x/y axes. Circle markers and text labels display the latest value of each line. Data comes from CSV files processed through a custom loadAndProcessData function.

Line Chart with Multiple Lines by Country

This line chart displays cumulative COVID-19 deaths over time for multiple countries, with each country represented by a randomly colored line. The chart uses a logarithmic y-axis to accommodate the wide range of death counts. Built with React and D3 v7, it employs `scaleTime` for the x-axis and `scaleLog` for the y-axis, creating paths with `d3.line`. Data comes from the COVID-19 Global Deaths time series on GitHub, processed via `d3.csv`.

Untitled

This line chart visualizes the daily count of global COVID-19 cases across multiple countries from January to April 2020. The code uses d3.csv to load the data and d3.time.scale and d3.scale.linear for the axes, with d3.svg.line and an interpolate("basis") curve for the paths. It animates the drawing of each country’s line using transition and stroke-dasharray. The line for Brazil is highlighted in green, while all other countries are drawn in black. Data originates from a global cases CSV file.

Melting Data for Multiple Lines

This example visualizes COVID-19 confirmed cases across several countries using multiple animated line charts. The visualization uses D3.js v5 with SVG rendering to display data from CSV files, showing how cases grow over days since the outbreak began. The implementation employs D3 scales for linear and time axes, the `nest()` function to group data by country, and `line()` with `curveBasis` to generate smooth paths. A color legend and animated transitions update the lines dynamically, while a custom `yValue` function adds random variance to China’s data for demonstration purposes.

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`.
