This visualization displays educational metrics across countries and regions, using the World Educational Data dataset from Kaggle. It renders the data as raw JSON in a `<pre>` element, with the dataset loaded via `fetch` and parsed using `d3.csvParse`. Each row’s numerical attributes, such as out-of-school rates, completion rates, and proficiency scores, are converted to numbers using the unary plus operator, and geographic coordinates (latitude and longitude) are also parsed. The visualization uses the D3 library for data loading and DOM manipulation via `select`, with state management handled through custom `setState` and `render` functions.
