This example loads a CSV dataset and computes the average age of children per country, displaying the result as a JSON summary using D3’s `flatRollup` and `sum`. The code demonstrates asynchronous data fetching with `fetch`, parsing via `csvParse`, and type coercion of numeric fields. It uses D3 v7 for data aggregation and DOM updates, selecting a container to render the computed summary as preformatted text. The visualization highlights a simple data-processing pipeline without graphical charts, focusing on aggregation logic and state management.

Activity 6 Task 4 Transforming Data

This visualization shows a JSON summary of average sepal length grouped by species, calculated from a CSV dataset. The code uses D3 v7 functions including `csvParse` to load data from `data.csv`, `flatRollup` and `sum` to aggregate the data, and `select` to render the resulting summary as a `<pre>` element. The visualization initially loads the CSV asynchronously, parses numeric fields, and then displays the computed group averages.

Assignment 1-Task10

This example loads a Human Development Index CSV from a GitHub gist and displays the first 10 rows as formatted JSON in a web page. It uses D3 v5’s `csv` and `csvFormat` functions to fetch and process the data, and `select` from D3 to append `<pre>` elements to the body. The visualization renders as static SVG text output, demonstrating basic data loading and inspection with a minimal interface.

National median age data visualization

This example visualizes national median age data for the USA in 2023, displaying the data as a simple text output in the browser. It loads the dataset from a remote CSV file hosted on GitHub using `d3.csv`, then applies the data to the page. The visualization uses D3 version 7, specifically importing the `select` function from the D3 module to manipulate the DOM and update the body text. The code is minimal, with no graphical charts or interactive elements, focusing solely on demonstrating data loading and basic DOM manipulation.

Datavis 2020 Assignment 2 - (Tutorials 12, 13 and 15)

This example demonstrates how to load and summarize a CSV dataset of US births from 1994–2014, reporting the row count, column count, and file size in kilobytes. The visualization uses d3.csv to fetch and parse the data, then displays the summary in an HTML pre element. The code also includes commented alternatives using the Fetch API with async/await and d3.csvParse, as well as an older nested-fetch pattern. The data merges CDC, NCHS, and SSA sources, with 2000–2003 values averaged between datasets.

Transforming Data

This example demonstrates how to transform the classic Iris dataset by computing the average sepal length for each species using `d3.flatRollup` and `d3.sum`, then displaying the aggregated results as a JSON summary in a `<pre>` element. The visualization loads CSV data asynchronously via `fetch`, parses it with `d3.csvParse`, and converts numeric fields before processing. Built with D3 v7 and ES6 modules, it showcases lazy state management where data is fetched and transformed only once on initial render.

Transforming Data

The visualization loads smartphone data from a CSV file and groups it by mobile model name, calculating the average price per model. It demonstrates data transformation with D3.js functions like `csvParse`, `flatRollup`, and `sum`, then outputs the aggregated summary as formatted JSON text within the container. The example highlights modular ES6 imports and asynchronous data fetching via `fetch`, rendering results in a simple text-based display using D3's `select` and `join` operations.

DATA VISUALIZATION

This example loads a CSV of country populations from a GitHub gist and displays a plain-text summary of the dataset in the browser. Using `d3.csv`, it fetches the data and then computes the file size in kilobytes, row count, and column count, which are formatted with `d3.csvFormat` and written to a `<pre>` element styled with black background and green text. The data originates from the 2018 United Nations World Population Prospects estimate, though the live code references a different gist URL than the documented file.

Transforming Data

This example demonstrates data transformation from a CSV file using D3.js. The visualization loads fruit pricing data and calculates the average sepal length for each species using `flatRollup` and `sum`. The transformed data is then rendered as a JSON string in a `<pre>` element. The code utilizes `csvParse` for data ingestion, `select` for DOM manipulation, and the `flatRollup` aggregation API to summarize the dataset.
