Forked from Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying the file size, row count, and column count in a large text format. It uses D3 v5’s `d3.csv` method with a promise-based `.then()` callback to fetch data from a CSS Named Colors dataset hosted on GitHub Gist. The code also includes commented-out alternatives using the Fetch API with `async`/`await` and `d3.csvParse`, as well as a nested “pyramid of doom” fetch pattern, showing different approaches to asynchronous data loading.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing a CSV file containing CSS named colors, displaying the file size, row count, and column count in large text. The code uses D3 v5’s `d3.csv` method with a promise to fetch and parse the remote CSV data. It also includes commented alternatives using the Fetch API with `async`/`await` and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern. The rendered output is a simple text summary within a `pre` element.

Fork of Loading and Parsing CSV Data

This example demonstrates the process of loading and parsing CSV data from a remote URL, displaying the file size, row count, and column count of the dataset. The code uses either the `d3.csv` method or the `fetch` API combined with `d3.csvParse` and async/await syntax to handle the data retrieval. The data source is a gist containing CSS named colors, and the results render as text in a large-format `pre` element. The example also includes commented-out code showing a nested Promise "pyramid of doom" pattern for comparison.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, then summarizes the dataset’s size in kilobytes, row count, and column count on a large text display. It uses D3 v5’s `d3.csv` method with a Promise-based `.then` callback to fetch the file, while commented-out alternatives show the same task using the Fetch API with async/await and `d3.csvParse`. The data comes from a GitHub gist containing CSS named colors. The page is minimal, relying on a `<pre>` element for output and no interactive charts.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote source using D3.js. It displays the file size, row count, and column count of the CSS Named Colors dataset in a large text format. The code uses `d3.csv` to fetch and parse the data asynchronously, then accesses the resulting parsed array and its `.columns` property. An alternative approach using `fetch`, `async`/`await`, and `d3.csvParse` is provided in comments, along with a deprecated callback-based "pyramid of doom" pattern.

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 how to load and parse CSV data using D3 v5 and native browser APIs. It fetches a dataset of CSS named colors from a GitHub gist and displays the file size in kilobytes, row count, and column count in a large text element. The primary implementation uses `d3.csv` with a promise-based `.then()` callback, while commented-out alternatives show the same task using `fetch`, `async/await`, and `d3.csvParse`. The code also includes a commented "pyramid of doom" example illustrating nested promise callbacks.

Fork of Loading and Parsing CSV Data

This example demonstrates the loading and parsing of CSV data from a remote URL, displaying the file size, row count, and column count as plain text. The code primarily uses D3.js version 5’s built-in `d3.csv` method, which returns a promise that resolves to parsed data. An alternative commented-out approach uses the Fetch API with `async`/`await` and `d3.csvParse` for manual parsing. The data comes from a gist containing CSS named colors, and the results appear in a large-font `<pre>` element.

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.
