This example visualizes the global cumulative death toll from COVID-19 over time as a single grey line chart. The visualization combines a React app for layout and component composition with D3 v5 utilities for scales and axis rendering. Data is fetched from a CSV maintained by the CSSE at Johns Hopkins, aggregated globally per day, with D3’s `csv` and `timeParse` handling ingestion. The chart uses D3’s `scaleTime` and `scaleLinear` for axes, `line` for the path, and `axisBottom` for the x-axis, while custom marker lines highlight the 5-million-death threshold and the final date.

CoronaVirus Line Chart with Axis

The chart shows the global cumulative death total from the COVID-19 pandemic over time, using a line path drawn with D3 v5’s `line` generator and scales from `scaleTime` and `scaleLinear`. Horizontal markers at 10,000, 100,000, 500,000, 1,000,000, and 2,000,000 deaths are rendered as rudimentary y-axis gridlines with labels, and the x-axis is built with `axisBottom` and custom tick sizing. Data comes from the Johns Hopkins University CSSE time series CSV, fetched via `d3.csv`, and the visualization is implemented as a React component rendering an SVG.

Corona Virus Linear Y Axis Chart (React + D3 Axis)

This example shows the cumulative global death toll from COVID-19 over time, plotted on a linear y-axis. The React component renders an SVG line chart using D3 scales (`d3.scaleTime`, `d3.scaleLinear`) and axes (`d3.axisBottom`, `d3.axisLeft`), with gridlines and annotation markers. It loads time-series data from a public GitHub CSV via `d3.csv`, aggregates daily totals, and draws the path with `d3.line`. The chart fills the viewport and updates automatically when the data arrives.

CoronaVirus Line Chart

A line chart displays the cumulative global death toll from COVID-19 over time, based on data from the CSSE at Johns Hopkins University. The chart marks the most recent date with a vertical “now” line and highlights thresholds at one and two million deaths with horizontal reference lines. Built with React and D3 v5, the visualization uses `scaleTime` and `scaleLinear` for axes, and `d3.line` to generate the SVG path from a dataset transformed from CSV by summing daily death totals across all countries.

CoronaVirus Line Chart

This visualization displays the global cumulative death toll from COVID-19 over time as a single black line chart. It uses a React component with D3 v5 scales (`scaleTime`, `scaleLinear`) and a `line` generator to plot data from the JHU CSSE COVID-19 time series dataset. Dashed horizontal markers label key thresholds (10,000 to 2,000,000 deaths) via a custom `YMarkerLine` component, which draws SVG `<line>` elements and formatted text labels. The chart fills the browser window and updates when new data is loaded.

CoronaVirus Linear Chart

Using D3 v5 within a React component, this chart visualizes global cumulative COVID-19 deaths over time from the JHU CSSE dataset. A single SVG line path traces the rising death totals, with gridlines and labeled axes generated by `d3.axisBottom` and `d3.axisLeft`. The code scales dates with `d3.scaleTime` and death counts with `d3.scaleLinear`, fetching data via `d3.csv` and formatting it with custom parsing and reduction logic.

Corona Virus Line Chart

This line chart visualizes the cumulative death toll from COVID-19 over time, with a single black line tracing the global trend. A horizontal marker at 10,000 and a vertical marker at the latest date provide visual reference points. Built with React and D3 v7, the chart uses `scaleTime`, `scaleLinear`, and a `line` generator to plot data from a CSSE GitHub CSV. The SVG rendering includes custom marker components for the annotations, and data is loaded asynchronously via `d3.csv`.

CoronaVirus Linear Y Chart

This example visualizes the global cumulative death totals from the COVID-19 pandemic over time using a linear y-axis line chart. The chart is built with React and D3 v5, using `d3.scaleTime` and `d3.scaleLinear` for the axes and `d3.line` to generate the SVG path. Data is loaded via `d3.csv` from a Johns Hopkins CSSE time-series dataset. The axes are rendered as reusable React components that call `d3.axisBottom` and `d3.axisLeft` inside `useEffect` hooks.

coronavirus Line Chart Practice

This example shows the global cumulative death toll from COVID-19 over time as a single black line chart, with horizontal and vertical marker lines highlighting the 10,000-death threshold and the latest date. Built with React and D3 v5, it uses `d3.csv` to load time-series data from the CSSE COVID-19 dataset, `scaleTime` and `scaleLinear` for axes, and `d3.line` to generate the path. The SVG is rendered directly via React components, while `d3.axisBottom` and refs are used to draw the x-axis.
