This example is a JavaScript tool that generates three synthetic CSV datasets for practice. It creates a bar chart dataset of 120 product sales, a scatter plot dataset of 150 height and weight observations, and a multi-series dataset of 200 monthly metric samples. The code uses the DOM `document.createElement` and `a.click()` API to trigger automatic file downloads of each CSV. It also leverages JavaScript's `Math.random` and `encodeURIComponent` for data generation and file encoding, all within a single HTML page.

This example demonstrates the loading and parsing of a CSV data file, displaying its file size, row count, and column count on a web page. It also embeds two static SVG images for visual context. The implementation uses the Fetch API to retrieve the remote CSV, then processes the response as a Blob and text to extract dimensions. The page styling relies on plain CSS, while the dynamic content is inserted into the DOM via `document.getElementById` and `innerText`. No external visualization libraries are used; the focus is on basic data inspection and layout.

Fork of Hello HTML

This example displays a CSV dataset loaded from a GitHub Gist, summarizing the total row count and previewing the first five records in an HTML table. It then renders an SVG bar chart showing the first column as categorical labels on the x-axis and the second column as quantitative values on the y-axis using `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. The chart title and axes are added via D3 selections. Styling uses embedded CSS, and data loading relies on `d3.csv`.

This example demonstrates a minimal HTML page that loads a CSV dataset of CSS named colors using D3.js. The page displays “Hello HTML” in large text while the CSV data is fetched asynchronously from a GitHub gist. It logs the total number of data rows to the browser console. The code uses `d3.csv()` to parse the remote CSV file, showing a basic data-loading pattern with a Promise-based callback.

This example displays monthly revenue and profit data from a CSV file, with the values rendered as large text in a styled HTML page. The visualization uses Bootstrap for responsive layout and styling, while custom CSS centers the output. JavaScript logs a message to the browser console, but the primary display relies on static HTML content rather than dynamic data binding. The page demonstrates a minimal setup combining HTML, CSS, and JavaScript without any charting library, highlighting the basic structure for future React or D3-based visualizations.

This example loads a CSV file containing names and ranks, then logs the resulting array of objects to the browser console using `d3.csv`. The page structure is minimal, with a single `div` container and a module script that executes the data-loading logic. Styling is applied via a CSS class for large centered text, though no visual rendering occurs in the current code. The project demonstrates a basic integration of D3.js v7 for asynchronous data parsing within a simple HTML and JavaScript setup.

This example demonstrates loading a remote CSV dataset and displaying basic information about it in the browser. It uses D3 v7’s `d3.csv` to fetch and parse the data, then computes the file size in kilobytes, row count, and column count. The result is written to a `<pre>` element via the DOM API, while a separate SVG chart is embedded as an image. The page also includes static HTML and CSS for layout, with the SVG rendered from the `shape.svg` file.

This example loads a small CSV dataset of color names from a remote URL and prints a summary of its size, row count, and column count into a preformatted text block. It uses d3.csv to fetch and parse the data, and d3.csvFormat to calculate the approximate file size. Below that, the page displays four static SVG circles, each filled with a hex color from the dataset and labeled with its color name. The page is a minimal React-free HTML document that combines D3 v7 with inline SVG rendering.

This example loads a cereal dataset from a GitHub gist and displays a data summary with column details, unique counts, and sample values, plus a preview table of the first five rows. It also renders a quick SVG mini bar chart showing the number of non-empty cells per row. The page uses d3.csv to fetch and parse the data, then manipulates the DOM directly to build the summary, table, and SVG visual without additional frameworks.
