Forked from Loading and Parsing CSV Data

This example displays summary statistics for a CSV dataset of all space missions from 1957, showing the file size in kilobytes, row count, and column count in large text. It loads the data using `d3.csv` with a promise, then calculates the metrics via `d3.csvFormat` and the parsed data’s `length` and `columns` properties. The code also includes commented alternatives using `fetch` with `async/await` and `d3.csvParse`, as well as a nested promise “pyramid of doom” pattern. The data source is a raw GitHub Gist URL.

Loading data "All Space Missions From 1957" by Enze Liu

This example loads a CSV file of all space missions from 1957 and displays basic dataset statistics in large text: file size in kilobytes, row count, and column count. It uses d3.csv to fetch and parse the data from a GitHub Gist, then reports the formatted file length and the parsed array’s dimensions. The code also includes commented alternatives using fetch with async/await and a nested promise chain, illustrating different loading approaches with D3 v5’s CSV parsing.

All Space Missions from 1957

This visualization displays metadata about a dataset of space missions from 1957: its size in kilobytes, row count, and column count. Using D3 v5, the code loads a remote CSV file via `d3.csv` and calculates the file size with `d3.csvFormat`, then renders the three numbers in a large `<pre>` element. The data originates from a Kaggle dataset covering rocket launching records up to the present day. The example also demonstrates alternative loading approaches using `fetch` and `d3.csvParse` in commented-out code.

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 a CSV file using D3.js, displaying summary statistics about the dataset in a large text format. The page fetches a sample CSV file from a GitHub Gist using the `d3.csv` method, which returns a promise with the parsed data. The code then calculates and presents the file size in kilobytes, the number of columns, and the number of rows by using `d3.csvFormat` to reconstruct the CSV text. The statistics are rendered in the browser via the `message-container` element using D3 v7.

Loading and Parsing CSV Data

This example demonstrates how to load and parse a CSV file using D3 v5, displaying the file size, row count, and column count in large text. It uses `d3.csv` to fetch and parse the dataset asynchronously via a promise, then formats a summary message with `d3.csvFormat` to calculate kilobyte size. The data source is a GitHub-hosted CSV containing CSS named colors. An alternate approach using the Fetch API with `async` and `await`, plus `d3.csvParse`, is included as commented-out code for comparison.

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 how to load and parse CSV data using D3.js, displaying summary statistics about the dataset. It fetches a CSV file containing CSS named colors from a GitHub gist and shows the file size in kilobytes, the number of rows, and the number of columns in a large preformatted text block. The primary implementation uses `d3.csv` with a promise, while commented-out alternatives illustrate using `fetch` with `async/await` and `d3.csvParse`. The example also includes a commented-out "pyramid of doom" pattern for comparison.
