Forked from Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying summary statistics about the dataset. It fetches a CSV file containing CSS named colors and reports the file size in kilobytes, the number of rows, and the number of columns in a large-text HTML element. The code uses `d3.csv` to fetch and parse the data, followed by `d3.csvFormat` and `data.length` to compute metrics. The page also includes commented-out alternatives using the Fetch API with async/await and `d3.csvParse`.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data from a remote URL, displaying summary statistics as large text. It fetches the CSS Named Colors dataset and shows the file size in kilobytes, row count, and column count. The visualization uses D3 v5’s `d3.csv` method to fetch and parse the data asynchronously, leveraging JavaScript promises. An alternative commented-out approach uses the Fetch API with `async`/`await` and `d3.csvParse` for the same purpose.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying summary statistics about the dataset. The code fetches a CSV file containing CSS named colors and calculates the file size in kilobytes, the number of rows, and the number of columns. It primarily uses `d3.csv` with a promise chain, while commented-out alternatives show the same task using `fetch`, `async`/`await`, and `d3.csvParse`. The results are rendered as large text inside a `<pre>` element, with the D3 library loaded via a CDN.

Fork of Loading and Parsing CSV Data

This example displays summary statistics about a CSV file containing CSS named colors. It loads the data from a remote URL and reports the file size in kilobytes, the number of data rows, and the number of columns as large text. The implementation uses D3 v5’s `d3.csv` and `d3.csvFormat` functions, alongside commented alternatives demonstrating the `fetch` API with `async`/`await` and the lower-level `d3.csvParse`. The data originates from a GitHub gist of CSS named colors.

Fork of Loading and Parsing CSV Data

This example displays basic statistics about a CSV dataset loaded from a remote URL, showing the file size in kilobytes, row count, and column count in large text. It uses D3 v5's `d3.csv` method to fetch and parse the CSS Named Colors dataset, then formats the results with `d3.csvFormat` and `Math.round`. The code also includes commented-out alternatives using the Fetch API with `async`/`await` and `d3.csvParse`, as well as a nested Promise-based approach. The page is a simple HTML document with D3 loaded from a CDN.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying summary statistics about the dataset in a large, readable text format. It uses the `d3.csv` method to fetch and parse the CSS Named Colors dataset, then reports the number of rows, columns, and approximate file size in kilobytes. The code highlights both a promise-based approach with `d3.csv` and an alternative commented-out implementation using `fetch` with async/await and `d3.csvParse`, showcasing different ways to handle data loading in D3 v5 within a React framework.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data from a remote URL, then displaying basic statistics about the dataset in a large text format. Using the D3.js library (version 5), the code employs the `d3.csv` function to fetch and parse the CSS Named Colors dataset, then reports the file size in kilobytes, the number of rows, and the number of columns. An alternative commented-out approach using the Fetch API with async/await and `d3.csvParse` is also included.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL using D3 v5 and the Fetch API. It displays a summary of the dataset—the CSS Named Colors file—showing file size in kilobytes, row count, and column count in large text. The code uses `d3.csv` to fetch and parse the data, then formats it with `d3.csvFormat` to compute the size. It also includes commented-out alternatives using `fetch`, `async`/`await`, and `d3.csvParse` to highlight different parsing approaches.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying the file size in kilobytes, row count, and column count as plain text. It uses the `d3.csv` function from D3 v5 to fetch and parse the CSS Named Colors dataset. The code also includes commented-out alternatives using `fetch`, async/await, and `d3.csvParse`, showing different approaches to handling asynchronous data loading. The visualization itself is minimal, prioritizing the data-loading process over graphical representation.
