Forked from Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3 and the Fetch API. It fetches a list of CSS named colors from a GitHub Gist and displays a summary of that dataset: the file size in kilobytes, the number of rows, and the number of columns. The code highlights two approaches: using `d3.csv` to fetch and parse directly, and an alternative method that uses `fetch` with `async`/`await` alongside `d3.csvParse`. A commented-out section shows an older "pyramid of doom" pattern. The results are rendered as large text in an HTML `<pre>` element, with a font size set via CSS.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing CSS Named Colors CSV data, displaying a summary of the dataset's size, row count, and column count in a large text element. It uses D3 v5’s `d3.csv` method to fetch and parse the remote CSV file from a GitHub gist, then formats the output with `d3.csvFormat`. The code also includes commented-out alternatives using the Fetch API with `async`/`await` and `d3.csvParse`, as well as a "pyramid of doom" pattern, highlighting different approaches to asynchronous data loading.

Fork of Loading and Parsing CSV Data

This example demonstrates the fundamentals of loading and parsing CSV data using D3.js version 5. It fetches the CSS Named Colors dataset from a GitHub Gist and displays a simple text summary of the file size in kilobytes, row count, and column count. The primary approach uses the `d3.csv` function to fetch and parse the remote CSV file, leveraging Promise-based asynchronous handling. The code also includes commented-out alternatives using native `fetch` with `async`/`await` and the `d3.csvParse` function, alongside a nested Promise "pyramid of doom" example. The output is rendered as large text within an HTML `<pre>` element.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3’s `d3.csv` method, fetching a dataset of CSS named colors from a GitHub gist. It displays the file size in kilobytes, the row count, and the column count in a large `<pre>` element. The code relies on the Fetch API and async functions to retrieve the text, while D3 handles parsing and formatting the data, with all results rendered directly into the DOM.

Fork of Loading and Parsing CSV Data

This example loads CSS named colors from a CSV file hosted on GitHub and displays a summary of the dataset as text. It uses D3 v5’s `d3.csv` method to fetch and parse the data, then reports the file size in kilobytes, the number of rows, and the number of columns. The code also includes commented-out alternatives using the Fetch API with async/await and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern for comparison. The rendered output is a simple `<pre>` element with large monospaced text.

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 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.

This example demonstrates how to load and parse CSV data using D3 v5 and the Fetch API. It fetches the CSS Named Colors dataset from a GitHub gist and displays the raw text in the browser console. The code includes multiple commented-out approaches, showing alternatives like `d3.csv` for direct parsing and the newer async/await syntax with `fetch` and `response.text()`. It highlights the progression from callback-based "pyramid of doom" patterns to modern promise chains.
