Forked from Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data using D3.js, displaying the data size in kilobytes, row count, and column count in a large text element. It uses the `d3.csv` method to fetch and parse the CSV file from a GitHub gist, then accesses the parsed data array and its `columns` property to calculate the metrics. The code also includes commented alternatives using `fetch` with `d3.csvParse` and a nested promise pyramid approach, though the active path runs the external DaData API POST request instead.

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 the process of loading, parsing, and summarizing a CSV file using the D3.js library’s `d3.csv` method. It displays the data’s size in kilobytes, total row count, and column count in a large text element. The data originates from a GitHub-hosted CSS named color dataset. The code also includes commented-out alternatives using `fetch` with async/await and the `d3.csvParse` function, though the active path uses `d3.csv` and `d3.csvFormat` to calculate the file size.

Loading and parsing CSV data wih D3

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()`.

Loading and parsing CSV

This example demonstrates how to load and parse a CSV file using D3.js, displaying the resulting dataset’s size in kilobytes, row count, and column count as large text on a plain HTML page. The code fetches a remote CSV file from a GitHub gist via `d3.csv`, then formats the parsed data with `d3.csvFormat` to calculate its size. It also reads the `data.length` and `data.columns.length` properties to report the number of rows and columns, updating the page’s `<pre>` element with `textContent`.

Loading Parsing CSV Data

This example demonstrates how to load and parse a CSV file, displaying file size, row count, and column count on a webpage. It uses d3.csv to fetch a remote dataset from a GitHub gist raw URL, then formats the results with d3.csvFormat to calculate kilobytes. The page also includes commented-out code showing an alternative approach using fetch, async/await, and d3.csvParse. A large pre element displays the final statistics as text.

Loading and Parsing CSV Data

This example demonstrates the basic process of loading and parsing CSV data by displaying the file size, row count, and column count of a remote dataset. It fetches a CSV file from a GitHub Gist using the `fetch` API, then parses it with `d3.csv` and re-formats it with `d3.csvFormat` to compute the kilobyte size. The parsed data’s dimensions are displayed in large text within a `<pre>` element. The code also includes an alternative commented-out approach using `d3.csvParse` on raw text.

Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data with D3, displaying basic metadata about the dataset. After fetching the CSV file from a GitHub gist, it computes and presents the file size in kilobytes, the total number of rows, and the column count. The visualization uses D3's `d3.csv` method to asynchronously fetch and parse the data, followed by `d3.csvFormat` to measure the raw text length. The resulting statistics are rendered as large text in an HTML `<pre>` element, with alternative commented-out approaches using `fetch`, `async`/`await`, and `d3.csvParse`.
