This example loads the Iris dataset from a CSV file and displays it as raw JSON text in a `<pre>` element. The visualization uses d3.csvParse to convert the CSV string into an array of objects, then coerces numeric columns to numbers. It demonstrates a state management pattern with d3-selection’s select and join methods, where data is asynchronously fetched and rendered after a loading state. The code shows only text output, not a graphical chart.

world-happiness-data

This example demonstrates the process of loading and parsing a CSV dataset containing measurements of iris flowers. The visualization initially shows a JSON representation of the parsed data, displaying all 150 records with their sepal and petal dimensions. The code uses D3's `csvParse` function to convert the raw CSV text into structured data, then converts the numeric string values to numbers. The `select` function and `.join('pre')` method render the data as text in the container, while the `fetch` API retrieves the data.csv file from the server.

world-happiness-data

This example visualizes the World Happiness Report data, showing how each country’s overall happiness score and rank relate to factors like GDP per capita, social support, and healthy life expectancy. The code loads a CSV file using D3’s `csvParse` (though the import initially references `tsvParse`) and displays the parsed data as a raw JSON object inside a `<pre>` element. It uses D3 v7’s `select` and `join` to manage the DOM, with a `setState` pattern to handle asynchronous data loading. The visualization currently only logs the first five rows to the console and prints the full dataset, not yet rendering any charts.

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 loading a CSV dataset by fetching the Iris Dataset from a remote URL and displaying its raw JSON structure in the browser. The code uses d3.json to retrieve the data, then chains a promise to append a `<pre>` element to the body, formatting the response with JSON.stringify and indentation. The visualization itself is minimal, focusing solely on the data-loading workflow rather than rendering charts or graphs. It relies on D3 v5’s `json` method and standard DOM selection via `select`, making the asynchronous data-fetching pattern explicit.

D3 data transformation

This example demonstrates a simple data-loading and transformation workflow using D3. It fetches a CSV file containing the classic Iris dataset and uses `d3.csvParse` to convert the raw text into an array of objects, subsequently coercing the numeric measurement columns to numbers. The resulting parsed data is displayed as formatted JSON inside a `<pre>` element. The visualization uses a minimal state management pattern, with a `setState` callback triggering re-renders, and leverages D3’s `select` and `join` for DOM updates.

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 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 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.
