Coronavirus Line Chart

Coronavirus Line Chart

This line chart visualizes the global cumulative COVID-19 death total over time, using a simple black line against a white background. A horizontal marker line highlights the point at which deaths reach one million. The visualization is built with React and D3 v7, using `scaleTime`, `scaleLinear`, and `line` to render an SVG path from a CSV dataset provided by the Johns Hopkins CSSE GitHub repository. The chart updates responsively to fill the full browser window.

Coronavirus line chart - global deaths

A line chart tracks cumulative global COVID-19 deaths over time, using data from the Johns Hopkins Coronavirus Dataset. The chart plots dates on a time scale and death totals on a linear scale, with a horizontal marker line highlighting the 500,000-death threshold. Built with React and D3 v5, the visualization uses `scaleTime`, `scaleLinear`, and `line` from d3 to generate an SVG path, while `csv` and `timeParse` handle data loading and date parsing.

Coronavirus Line Chart

A line chart tracks global cumulative COVID-19 deaths over time, using a logarithmic y-axis to show growth across multiple orders of magnitude. Built with React and D3 v6, it fetches live data from the Johns Hopkins CSSE GitHub repository via `d3.csv`. The chart renders as SVG, with scales created by `scaleTime` and `scaleLog`, axes via `axisBottom` and `axisLeft`, and a tomato-colored `MarkerY` annotation highlighting the 10,000-death threshold.

Coronavirus Line Chart with Marker Lines Part I

This line chart displays global cumulative COVID-19 deaths over time from the Johns Hopkins dataset, with a horizontal marker line at the one-million-death threshold. The React component uses D3 v6 functions `scaleTime`, `scaleLinear`, `extent`, `max`, and `line` to construct an SVG path. Data loading relies on `csv` and `timeParse` to transform daily country-level death counts into aggregated totals. The marker line is drawn as an SVG `<line>` element, while the path is unstyled except for a black stroke defined in the page’s CSS.

Coronavirus Line Chart

This line chart displays the total global COVID-19 deaths over time, based on data from the CSSE at Johns Hopkins University. It includes a vertical marker at the most recent date and a horizontal reference line at 6.5 million deaths. The visualization is built with React and D3 v5, using `scaleTime`, `scaleLinear`, and the `line` generator to render an SVG path. The CSV data is loaded and transformed with `d3.csv` and `timeParse`.

Coronavirus Line Chart with Marker Line

A line chart visualizes the global cumulative total of COVID-19 deaths over time, with a horizontal marker line positioned at one million deaths. The chart uses React to render an SVG, with scales and line generation handled by d3.scaleTime, d3.scaleLinear, and d3.line. The data comes from a CSV file provided by the COVID-19 Data Repository at Johns Hopkins University, loaded via d3.csv and transformed by grouping daily death totals.

Coronavirus Line Chart

The chart displays the cumulative global death toll from COVID-19 over time as a single black line, with a horizontal marker line indicating the 10,000-death threshold. Built with React and D3 v7, it uses `scaleTime` and `scaleLinear` to map dates and totals, while a `line` generator produces the SVG path. The data is fetched from the CSSE COVID-19 time series CSV, aggregated daily by summing deaths across all countries.

Coronavirus Line Chart with D3 Axes

A line chart visualizes the cumulative global COVID-19 death toll over time using the John Hopkins Coronavirus Dataset. It plots daily death totals on a linear scale and dates on a time scale, with a red marker line highlighting the 1 million death milestone and an "now" marker at the most recent date. The chart is built with React and renders SVG paths using D3 v5’s `scaleTime`, `scaleLinear`, and `line` generators, while axes are drawn declaratively via `axisBottom` and custom marker-line components. Grid lines are styled with CSS.
