Loading and Parsing CSV Data

Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data using D3 v5. It displays the file size, row count, and column count of a wildlife trade dataset pulled from a GitHub gist. The primary approach uses `d3.csv`, which fetches and parses the CSV in one step, while commented-out alternatives show `fetch` with `async`/`await` combined with `d3.csvParse`. The results appear as large text in a `pre` element, providing a simple, immediate visual summary of the dataset’s basic dimensions.

This example demonstrates how to load and parse CSV data using D3 v5, displaying file size, row count, and column count in a large pre-formatted text element. The code uses `d3.csv()` to fetch and parse the dataset from a GitHub-hosted CSV file containing NYC social media usage data, then formats the statistics with `d3.csvFormat()` to calculate kilobyte size. An alternative commented-out approach uses the Fetch API with `async`/`await` and `d3.csvParse()` for manual parsing. The example concisely shows the core workflow of retrieving and inspecting tabular data in a browser environment.

Loading and parsing CSV data

This example demonstrates loading a remote CSV file and parsing it with D3.js, displaying basic dataset statistics as large text. It uses `d3.csv` to fetch and parse the data from a GitHub Gist, then reports the approximate size of the formatted output in kilobytes, the number of rows, and the number of columns. The page also includes commented-out code showing an alternative approach using the `fetch` API with `async`/`await` and `d3.csvParse` for manual text parsing, but the active path relies on D3's built-in CSV handling.

Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL using D3 v5. It displays the file size in kilobytes, the number of rows, and the number of columns in a large text element. The code uses `d3.csv` to fetch and parse the data, then accesses the resulting array’s `length` and `columns` properties. It also relies on `d3.csvFormat` to compute the formatted size, with an alternative commented approach using `fetch`, `async/await`, and `d3.csvParse`. The data comes from a GitHub gist containing named colors.

This example demonstrates how to load and parse CSV data using D3 v7. It displays the row count, column count, and file size in kilobytes as large text on the page. The code uses `d3.csv()` to fetch and parse a CSV file from a GitHub gist, then processes the resulting data array and columns. It also includes commented-out alternatives using `fetch()` with `async/await` and `d3.csvParse()` to illustrate older parsing approaches.

Loading and Parsing CSV Data

This example demonstrates the loading and parsing of CSV data using D3 v6, displaying the file size, row count, and column count in a large text element. The code fetches a CSV file from a GitHub gist containing named CSS colors and processes it with `d3.csv()`, which returns a promise. The results are formatted using `d3.csvFormat()` to calculate the data’s kilobyte size, while `data.length` and `data.columns.length` report the row and column totals. A commented section also shows an alternative approach using the Fetch API and `d3.csvParse()`.
