This gallery example displays the World Happiness Report 2019 data, presenting each country’s happiness score alongside contributing factors such as GDP per capita, social support, and healthy life expectancy. The visualization loads the data from a CSV file and displays the raw parsed JSON, demonstrating the initial data-loading phase. It uses d3.v7’s `select`, `csvParse`, and `fetch` API to retrieve and parse the dataset, updating the view through a state management system.

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.

World Happiness Dataset Schnair

This example displays the raw World Happiness Report 2019 data in a simple text format. The visualization initially loads a CSV file containing happiness scores and related metrics for various countries, parsing the data into a structured format. It uses the d3.csvParse API to read the data, then displays the parsed JSON representation of each country's record. The code demonstrates a basic data-loading workflow with d3.v7, showing how fetched data transitions from an undefined state to a formatted output using select and join methods.

World Happiness Report 2020 Data

This visualization parses the World Happiness Report 2020 CSV dataset to display basic file metrics: its size in kilobytes, row count, and column count. The code uses `d3.csv()` to load and parse the remote CSV, then `d3.csvFormat()` to measure its length. The results are rendered as large text inside a `<pre>` element, demonstrating a minimal data-loading workflow with D3 v5. The underlying dataset originates from Kaggle and contains happiness scores alongside GDP, life expectancy, social support, and freedom indicators for correlation analysis.

viz-happiness-2024

This example displays the raw data from the World Happiness Report 2024 as a formatted JSON preview, showing country names and their associated happiness indicators including Ladder score, social support, and GDP per capita. The visualization loads data from a CSV file using the `fetch` API and parses it with `d3.csvParse`, converting numeric fields from strings to numbers. The code renders the parsed data structure in a `<pre>` element, providing a simple text-based investigation of the dataset before any graphical mapping is applied. The implementation follows a state management pattern where data loading triggers a re-render of the view.

World Happiness Report

This example displays the World Happiness Report dataset, summarizing its size and previewing the first ten rows. It shows the number of rows, columns, and file size in kilobytes, followed by a JSON-formatted listing of the initial data entries. The page renders this textual information in a terminal-style interface with a black background and green monospace text. It uses D3 v5 functions such as `select`, `csv`, and `csvFormat` to load and process the CSV data from a remote Kaggle source, then appends the results as `<pre>` elements to the body.

World Happiness Report

This example displays the raw contents of the first row from the World Happiness Report 2019 dataset, rendering it as formatted JSON text. The code loads the data via an ES module import, converts six quantitative attribute columns to numbers, and then uses `JSON.stringify` to pretty-print the row inside a `<pre>` element. It relies on standard JavaScript data parsing and DOM manipulation without any external visualization libraries.

World Happiness 2017

This example prints a textual summary of the World Happiness 2017 dataset, showing row and column counts, file size, and the first ten rows as JSON. It loads the data from a CSV using `d3.csv`, formats it with `csvFormat`, and renders the output to the DOM via `d3.select` and `append`. The data originates from Kaggle, credited to the World Happiness Report.

World Happiness Report

This visualization displays the relationship between a country’s happiness score and its GDP per capita, with each circle colored by whether the country is classed as the “happiest country.” Built with the vega-lite-api and D3 v5, it loads CSV data from a GitHub gist and renders a scatterplot using `vl.markCircle`. The chart applies custom axis and label styling from a shared config, uses a tooltip to show country names, and fits the view to the window dimensions.
