This example demonstrates how to load and parse CSV data with D3.js. It reads the classic Iris dataset, which contains measurements of sepal and petal dimensions for three iris species, and displays the parsed data as a JSON object on the page. The code uses `d3.csv` to fetch the file, applies a row conversion function to coerce numeric fields from strings to numbers, and then logs the result to the console while rendering it in a `<pre>` element for visual inspection.

Part of the video course: D3.js in Motion.

An example of reading CSV data using D3.

This shows the "Iris" dataset. Originally published at UCI Machine Learning Repository: Iris Data Set, this small dataset from 1936 is often used for testing out machine learning algorithms and visualizations. Each row of the table represents an iris flower, including its species and dimensions of its botanical parts, sepal and petal, in centimeters.

Load CSV

This example demonstrates how to load and parse a CSV file using D3.js v4. The page fetches the classic Iris dataset from a local CSV file and uses the `d3.csv` method with a row-accessor function to convert numeric string values into numbers for all four measurement columns (petalLength, petalWidth, sepalLength, sepalWidth). The parsed data is then logged to the browser console. This simple yet essential example highlights D3's data-loading capabilities, showing how raw CSV text is transformed into an array of JavaScript objects with properly typed fields, ready for further visualization or analysis.

Loading Data

This example demonstrates how to load and parse a CSV file in D3.js, displaying the Iris dataset as formatted JSON text in a `<pre>` element. The visualization initially shows a "LOADING" state, then fetches `data.csv` via the Fetch API and parses it using `d3.csvParse`. The code explicitly converts string measurements into numbers for all four numeric columns. State management is handled through a simple `setState` pattern, where the `viz` function checks whether data is loaded, triggers the asynchronous fetch, and re-renders once the parsed array of objects is available.

Loading CSV

This example demonstrates how to load and display a CSV dataset using D3. It fetches the Iris Dataset from a remote URL and renders the parsed data as a JSON-formatted text block within the page. The code uses `d3.csv()` to asynchronously retrieve and parse the CSV file, then chains `.then()` to append a `<pre>` element to the body via `d3.select()`. The resulting output shows the structured data, making the loading and parsing process visible.

Loading Data

This example demonstrates how to load and parse a CSV file in D3.js, displaying the raw parsed data as a stringified JSON object in a `<pre>` element. The visualization uses a state management pattern with a `setState` function to handle asynchronous data loading, initially showing a "LOADING" placeholder. It fetches `data.csv`, parses it with `d3.csvParse`, and converts numeric columns to numbers before updating the display. The Iris flower dataset is used as the data source, with the rendering approach being a simple text-based output rather than a graphical chart.

Loading CSV

This example demonstrates how to load and display the Iris Dataset as raw JSON text on a webpage. It uses D3 v5’s `csv` function to fetch the remote CSV file, then converts the parsed data into a formatted JSON string via `JSON.stringify` and appends it to the body inside a `<pre>` element. The code relies on D3’s `select` method to target the document body for the output, showcasing a minimal workflow for fetching external tabular data and inspecting its structure.

Loading and Parsing CSV data

This example demonstrates how to load and parse CSV data using D3.js, displaying a summary of the loaded dataset in a large text element. It fetches the classic Iris dataset from a GitHub gist via `d3.csv`, then reports the file size in kilobytes, row count, and column count. The visualization also includes commented-out alternative code using the Fetch API with `async/await` and `d3.csvParse`, highlighting two approaches for handling CSV data in D3 v7 within a minimal HTML page.

The Iris Dataset

This example presents a minimal D3.js visualization that loads the classic Iris flower dataset from a CSV file (iris.csv) and displays its contents as raw, formatted JSON text on the page. Using the `d3.csv` method with a type conversion function, the code converts the numeric measurement columns to numbers before rendering the complete dataset structure with `JSON.stringify`. The simple output is intended as a starting point for testing data-loading workflows, showcasing 150 rows of sepal and petal measurements across three iris species from the UCI Machine Learning Repository.

Loading CSV

This example demonstrates loading an external CSV dataset—the Iris Dataset—and displaying its contents as formatted JSON in the browser. Using D3 v5’s `csv` function, it fetches the data asynchronously and, upon resolution, appends a `<pre>` element to the body with `JSON.stringify` to render the parsed array with indentation. The code imports `select` and `csv` directly from the D3 module, relying on Promises to handle the data load.
