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 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 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 D3 Axis

This chart visualizes global COVID-19 death totals over time using a line path, with a horizontal marker at the 1 million death threshold and a vertical marker at the most recent date. The React component uses D3 scales (scaleTime, scaleLinear) and a line generator to map the Johns Hopkins dataset, while custom XAxis and marker components render grid lines and labels. SVG output displays the path with a bold black stroke, styled tick marks, and formatted date labels.

Coronavirus Line Chart

A line chart tracks cumulative global COVID-19 deaths over time, using a black, five-pixel-wide path scaled to the full window. A horizontal marker at four million deaths and a vertical “now” marker at the latest date highlight key thresholds. The visualization is built with React components and D3 v7, using `scaleTime`, `scaleLinear`, and `line` for the path, plus `axisBottom` and `axisLeft` for gridlines. Data comes from a CSV of Johns Hopkins global death counts, aggregated by day and rendered as SVG.

Coronavirus Line Chart with Marker Line

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 w/ 1M Marker

This chart depicts the cumulative global death toll from COVID-19 over time, using data from the Johns Hopkins Coronavirus Dataset. A thin horizontal line marks the point where deaths reach one million, while a thick black path traces the rising trend. The visualization is built with React and D3 v6, using `scaleTime`, `scaleLinear`, and `line` to generate an SVG path. Data is loaded via `d3.csv` and processed by summing daily country-level death counts.
