This example demonstrates three core methods for loading and parsing CSV data in D3, displaying file size, row count, and column count as large, plain text. Using CSS Named Colors data from a GitHub gist, it shows the concise `d3.csv` API first, then provides commented alternatives using `fetch` with `async`/`await` and `d3.csvParse`. The visual output is purely typographic, rendered in a `<pre>` element, emphasizing the programming workflow over chart construction. The code relies on D3's `d3.csv` and `d3.csvFormat` functions, alongside standard JavaScript fetch operations.

Fork of Loading and Parsing CSV Data

This example demonstrates the basic mechanics of loading and parsing CSV data in D3. It fetches a dataset of CSS named colors from a GitHub gist and displays three summary statistics: file size in kilobytes, row count, and column count. The primary implementation uses D3 v5’s `d3.csv` method, which returns a promise, while commented alternatives show equivalent code using the Fetch API with `async`/`await` and `d3.csvParse`. The output is rendered as plain text inside a large `<pre>` element.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3 v5. It fetches a dataset of CSS Named Colors from a GitHub gist and displays key statistics: the file size in kilobytes, the number of rows, and the number of columns. The code primarily uses `d3.csv()` with a Promise-based `.then()` callback, though commented-out alternatives show fetching text with `fetch()` and `async/await`, plus `d3.csvParse()` for manual parsing. The output renders as plain text inside a `<pre>` element.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data, displaying the file’s size in kilobytes, row count, and column count as large text. It uses D3 v5’s `d3.csv` and `d3.csvFormat` to fetch and process the data, with commented alternatives showing `fetch`, `async/await`, and `d3.csvParse`. The data comes from a GitHub gist of CSS named colors, and the results update a single `<pre>` element without any visual chart.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data by displaying the file size, row count, and column count of a CSS Named Colors dataset pulled from a GitHub gist. It uses the D3 v5 `d3.csv()` method to fetch and parse the data asynchronously, then formats the summary with `d3.csvFormat()` and updates the page via `document.getElementById()`. Commented-out alternatives show equivalent approaches using the Fetch API with `fetch()` and `response.text()`, alongside `d3.csvParse()` and `async`/`await` syntax.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing a CSV file containing CSS named colors, displaying the data’s size, row count, and column count in a large text block. It uses D3 v5’s `d3.csv` method to asynchronously fetch the remote dataset, then `d3.csvFormat` and `data.columns` to compute metrics. The code also includes commented alternatives using the Fetch API with `async`/`await` and `d3.csvParse`, illustrating different parsing strategies. The rendering is plain HTML text within a `<pre>` element, with no graphical visualization.
