This visualization displays global COVID-19 death totals over time as a single bold line, with a horizontal marker line highlighting the one-million-death threshold. The React component uses d3.scaleTime and d3.scaleLinear to map dates and cumulative deaths to SVG coordinates, while d3.line generates the path. Data comes from the CSSEGISandData COVID-19 time-series CSV, loaded via d3.csv and aggregated daily. The marker line is a static SVG `<line>` positioned using the y-scale’s output for one million deaths.

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 with Marker Line

This line chart displays the global cumulative COVID-19 death toll over time from the Johns Hopkins dataset, with a vertical marker line at the current date and a horizontal marker line at the one-million-death threshold. The visualization uses React to render an SVG path generated by d3.line, with d3.scaleTime and d3.scaleLinear mapping dates and death totals. Marker lines are drawn as separate React components (XMarkerLine, YMarkerLine) using d3 scales for positioning, while the data is loaded and parsed via d3.csv.

Coronavirus Line Chart with 1M marker line

This chart shows the global cumulative COVID-19 death toll over time, with a horizontal marker line at the one-million-death threshold. The line chart uses d3.scaleTime for dates, d3.scaleLinear for deaths, and d3.line to generate the path. A horizontal `line` element is positioned using the y-scale’s value for 1,000,000. Data comes from the CSSE COVID-19 time series CSV, aggregated daily across all countries, and renders as an SVG in a React component.

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 with Marker Lines Part II

This chart displays cumulative global COVID-19 deaths over time as a line path, with marker lines highlighting the one million death threshold and the current date (“Now”). The code uses d3.scaleTime, d3.scaleLinear, and d3.line to generate the SVG path from the Johns Hopkins Coronavirus Dataset, which is loaded via d3.csv. React manages the component state, while custom XMarkerLine and YMarkerLine components draw the annotated reference lines.

Coronavirus Line Chart With 1M Marker

A line chart tracks cumulative COVID-19 deaths worldwide over time, using data from the Johns Hopkins Coronavirus Dataset. A horizontal black marker line highlights the point where total deaths reach one million. The visualization is built with React and D3 v5, employing `scaleTime`, `scaleLinear`, and `line` to generate the SVG path, while a separate `<line>` element marks the one-million death threshold. Data is loaded via `csv` and transformed by summing daily death totals across all countries.

Coronavirus Line Chart With 5,000,000 Marker Line

A line chart displays worldwide cumulative COVID-19 deaths over time, with a horizontal marker line highlighting the 5,000,000 death milestone. The chart uses a React component with D3’s `scaleTime`, `scaleLinear`, and `line` generator to map dates and death totals to SVG coordinates. The marker line is positioned using `yScale(5000000)`. Data comes from the CSSEGISandData COVID-19 time series CSV, aggregated by summing daily global deaths. The SVG renders the trend as a black stroke and the threshold as a thinner line, filling the browser viewport.

Coronavirus Line Chart With 5,000,000 Marker Line

A coronavirus line chart tracks cumulative global deaths over time, with a horizontal marker line highlighting the 5,000,000-death threshold. The SVG visualization uses React to render a black path generated by d3.line, scaled with d3.scaleTime and d3.scaleLinear. Data comes from the CSSE COVID-19 time series CSV, aggregated daily via d3.csv and timeParse. The marker line is explicitly positioned using the y-scale’s output for 5,000,000, emphasizing the milestone against the full death-total trajectory.
