Forked from Loading Data

This example loads a Gapminder life expectancy dataset in wide format and displays the raw parsed data as a JSON preview. It fetches `data.csv`, converts year columns to numbers, and handles values with a "k" suffix by multiplying by 1000. The visualization uses D3 v7's `csvParse` and `select` to manage asynchronous data loading and rendering. It demonstrates a data-loading workflow where the state tracks loading status and updates the view accordingly, without yet showing a chart.

AI-generated description

Gapminder Life Expectancy This dataset contains life expectancy data at birth for countries from 1800 to 2100. Sourced from the Gapminder Foundation, this data is also in a "wide" format, with years as columns. It's a classic example for creating visualizations that show how life expectancy has changed globally over a long time span.

Source URL: https://www.gapminder.org/data/

Attribute Descriptions country: Categorical (The name of the country).

Years (1800 through 2100): Quantitative and Temporal (The life expectancy value for each corresponding year).

Loading and Parsing Life Expectancy CSV Data

This example loads a World Health Organization life expectancy dataset from a GitHub gist and parses it with `d3.csv` (D3 v5). It displays the resulting dataset’s size in kilobytes, the number of data rows, and the number of columns as large text in a `<pre>` element. The code also includes commented alternatives using `fetch` with `d3.csvParse` and an async/await pattern, though only the primary `d3.csv().then()` path is active. The visualization is purely informational, summarizing the CSV’s structure without drawing charts.

“A — Life Expectancy (Loader)”

This example demonstrates a minimal data loader for global life expectancy data from Our World in Data (UN WPP 2024), using a subset of years from 2000 onward. The visualization shows the first five parsed rows in a simple HTML display, confirming that the CSV data has been loaded and formatted correctly. The code uses D3 v7’s `d3.csvParse` to convert raw text into objects with categorical, time, and quantitative attributes, and employs `d3.select` to manage the container. It serves as a foundation for future visualizations, with a clear separation between data loading and rendering logic.

Gapminder GDP per Capita

This example loads a Gapminder GDP dataset in wide format and displays the raw parsed data as JSON in the browser. It uses D3 v7’s `csvParse` to convert the CSV into an array of objects, then transforms string values like `"10.1k"` into numeric GDP per capita figures. The visualization fetches the remote CSV via `fetch`, processes the year columns from 1800 to 2100, and relies on a state management pattern with a `setState` function to trigger re-renders. The current implementation is a data-loading scaffold, not a finished chart.

Loading CSV Data with D3

This example loads a CSV dataset of country statistics and renders a bar chart of life expectancy using D3. The bars are sorted in descending order by life expectancy, with each rectangle’s width proportional to the value from the `Lifeexpectancyatbirth` column. The visualization uses `d3.csv` for data parsing, `d3.select` to build the SVG, and `.data()` with `rects` to create the graphical marks. The CSV file includes country names and numerical indicators, and a tooltip on each bar shows the country and its life expectancy.

Gapminder Clone

This interactive visualization recreates the classic Gapminder chart, plotting GDP per capita against life expectancy for countries over time from 1800 to 2014. Users can filter by continent via a custom dropdown menu and animate the progression through years with a play button. The code uses D3 v7 scales, axes, and transitions for the SVG rendering, with a tooltip displaying country details on hover. Data is loaded as JSON from an external GitHub source, and a custom dropdown module handles the continent selection.

Fork of GapMinder (CP341 Style)

This fork of GapMinder visualizes country-level income, life expectancy, and population across 1800–2008, with a scatterplot for a selected year and a second panel tracing each country’s life-expectancy trend over time. A slider and continent dropdown filter the data, while hovering highlights a country’s path and shows a tooltip with exact values. The visualization uses d3.v6 with SVG, scales like `d3.scaleLog` and `d3.scaleLinear`, and transitions via `transition().duration()`. It loads JSON data from a raw GitHub source, with historical annotations appearing at specific years.

Fork of Loading Data - Lifestyle Health

This visualization demonstrates how to load and parse a CSV dataset using D3 v7, displaying the raw parsed data as JSON in a `<pre>` element. The example uses `csvParse` to convert survey data about lifestyle and health metrics, explicitly coercing numeric fields with the unary `+` operator. A state management pattern handles asynchronous data loading, showing a 'LOADING' placeholder before the fetched dataset appears. The code relies on `select` and `join` to render the data, sourced from a Kaggle dataset on disease risk from daily habits.

Loading and Parsing Hans Rosling Population Growth Data

This example demonstrates loading and parsing the Gapminder total population CSV dataset used in Hans Rosling’s animated charts, displaying file size, row count, and column count as large text. It uses D3 v5’s `d3.csv` method to fetch and parse the remote data, then formats the resulting array with `d3.csvFormat` to measure its size. The code also includes commented alternatives using the Fetch API with `async`/`await` and a nested promise chain, showing multiple approaches to asynchronous data loading.
