Working with Time

This scatter plot visualizes weekly temperature readings in San Francisco, using time on the x-axis and temperature on the y-axis. The React-based visualization renders SVG circles, with axes built using D3’s `scaleTime` and `scaleLinear` APIs and tick generation via those scales’ `.ticks()` methods. Each circle includes a native SVG `<title>` tooltip showing the formatted timestamp. Data is loaded asynchronously from a CSV file using D3’s `csv` function and parsed with a custom row conversion, while `extent` and `.nice()` determine the scales’ domains.

Working with Time

This example visualizes a week of temperature readings in San Francisco, plotting each measurement as a dot along a time-based x-axis and a temperature-based y-axis. The scatter plot uses D3’s `scaleTime` and `scaleLinear` to map data to SVG coordinates, while React components render the axes and circular marks. The data is loaded via D3’s `csv` from a GitHub-hosted CSV file, and each circle includes a `<title>` tooltip formatted with D3’s `timeFormat` to show the specific day.

Working with time

A scatter plot displays temperature readings from a week of San Francisco weather data, with time on the x-axis and temperature on the y-axis. The visualization uses React to render SVG circles, with d3.scaleTime and d3.scaleLinear handling the scales. d3.axisBottom and d3.axisLeft are replaced by custom React components for tick marks, while d3.csv loads the dataset and d3.timeFormat formats the day labels. The chart highlights the daily temperature variation across the week.

Working with Time

A scatter plot displays San Francisco temperature readings over one week, with time on the x-axis and temperature on the y-axis. Each point represents a measurement, and hovering reveals the exact day via a tooltip. The visualization uses React to render SVG elements, with d3.scaleTime and d3.scaleLinear for scaling, d3.extent for domain calculation, and d3.csv for loading the Data Canvas Sense Your City dataset. Custom axis components generate ticks and labels, while circular marks encode the data points.

Working with Time

This example visualizes a week of temperature readings in San Francisco as a scatter plot, with time on the x-axis and temperature on the y-axis. Each circle represents a single measurement, and hovering reveals the exact timestamp. Built with React and D3 v5, the visualization uses `scaleTime` and `scaleLinear` to map data to SVG coordinates, while custom `AxisBottom` and `AxisLeft` components render the ticks. The code loads data from a CSV file containing the "Data Canvas Sense Your City" dataset and formats the time axis using `timeFormat("%a")` for day abbreviations.

Working with Time

A scatter plot displays one week of San Francisco temperatures, with time on the x-axis and temperature on the y-axis. The visualization uses a React and SVG structure with d3.scaleTime and d3.scaleLinear for scales, d3.extent for domain calculation, and d3.timeFormat for tick labels showing abbreviated weekdays. Circles are rendered and colored with a teal fill, and hovering reveals the exact timestamp via a `<title>` tooltip. The data is loaded asynchronously from a CSV using d3.csv.

Working With Time

This example shows a scatter plot of temperature readings over the course of a week, using a time-based x-axis and a linear y-axis for temperature. The data is loaded from a CSV file containing timestamps and temperatures for San Francisco, fetched via the `csv` function from `d3`. The visualization uses `d3.scaleTime` and `d3.scaleLinear` to map data to SVG coordinates, with React components rendering the axes and circular marks. Each point includes a tooltip showing the corresponding day of the week, generated with `d3.timeFormat`.

Working with time

This example visualizes the daily temperature of a week in San Francisco using a time-series scatter plot, with points connected by a line to highlight trends. The chart uses D3 scales (`scaleTime`, `scaleLinear`) to map timestamps and temperature values to SVG coordinates, with React managing the rendering of axes and marks. The data is loaded via D3’s `csv` parser from a remote file, and each point includes a tooltip showing the day of the week via `timeFormat`.
