This example presents a bar chart of country counts by continent, loaded from a CSV file via `fetch` and parsed with `d3.csvParse`. Each continent’s bar width is scaled proportionally to its country total, with counts displayed inside the bars, alongside a summary panel showing file size, row count, and column names. The visualization uses D3 v7 to update SVG rectangles and text elements directly via `getElementById` and `setAttribute`, while the static layout and styling are defined in HTML and CSS.

Fork of D3 Starter

This fork of the D3 Starter demonstrates a minimal bar chart that displays population data for several countries, sourced from a local CSV file. The visualization maps each country to a rectangle, with the height and width fixed while the data is read and logged. Built with d3.v7, the example uses `csv`, `scaleLinear`, `max`, and `select` APIs to parse data and prepare scales, though the rendered rectangles do not yet reflect the data values. The chart is drawn as SVG within a 960x500 canvas, with the data population values multiplied by 1000 during preprocessing.

Fork of HTML Starter

This example displays a static bar chart of country populations, reading from a CSV file with `d3.csv` and rendering rectangles with `d3.selectAll` and `data.join`. It uses D3 v7 within a plain HTML page, with data loaded asynchronously and converted to numbers. The visualization demonstrates basic data binding and SVG shape creation, though the rendered bars are all fixed at 300 by 300 pixels, so the chart does not reflect population values visually.

A horizontal bar chart displays population figures for nine countries, sourced from an embedded CSV file. The bars render as SVG rectangles, with each country's population scaled linearly along the x-axis and country names positioned using a band scale on the y-axis. The code uses d3.csv to load the data, d3.scaleLinear for the width mapping, d3.scaleBand for categorical spacing, and d3.select to append the rectangles.

This example shows a horizontal bar chart of the number of cases across several countries, with the data loaded from a CSV file. The bars display values in a compact format using D3's `format` with the `~s` specifier. The chart uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis categories, and `d3.axisLeft` and `d3.axisBottom` for the axes, all rendered as SVG. The code also applies margins, a title, and axis labels, with styling defined in a separate CSS file.

This bar chart displays country values using D3 v7, with each country represented as a vertical bar on an SVG canvas. The visualization uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` for tick rendering. Data comes from a static JavaScript array in `constants.js`. The chart includes rotated x-axis labels and an additional scrollbar implemented via a `foreignObject` element, though the scrollbar’s interaction is limited within the fixed-width SVG.

This example presents a bar chart of website engagement metrics from a CSV file, showing the number of views for each page path. The chart uses D3 version 7 to create a linear x-axis scale for view counts and a banded y-axis for page names. Users can toggle individual bars on and off using checkboxes rendered alongside a list of the data points. The visualization renders with SVG and derives its data dimensions from the imported `csv` and `scaleBand` functions.

This example demonstrates a basic bar chart using D3 version 7, with data loaded from a CSV file containing yearly values. The visualization renders an SVG with a band scale for the x-axis and a linear scale for the y-axis, displaying bars for each year. The code uses `d3.csv` to asynchronously load the dataset, then applies `d3.axisBottom` and `d3.axisLeft` to generate labeled axes. The y-axis ticks are formatted with a dollar sign prefix, and bars are drawn as `rect` elements sized by the scales.

This example demonstrates the data-loading process for a garden dataset, displaying summary statistics including file size in kilobytes, row count, and column count within a styled summary box. The visualization uses D3 v7’s `d3.csv` method to parse a CSV file fetched from a GitHub Gist, routed through a proxy URL to bypass CORS restrictions. A static SVG circle provides decorative context, while the script dynamically updates the DOM via `d3.select` and `textEl.html`. Error handling displays failure messages if the fetch or parsing encounters issues, and the console logs the first five rows for verification.
