Hello Sir

This example demonstrates how a D3.js visualization can combine DOM manipulation with external JSON data. It uses D3’s `select` function to insert a text message into an HTML div, while simultaneously loading vehicle registration data from the Dutch RDW via a remote endpoint. The code imports D3 through a CDN and also leverages local ES6 modules to organize the message string. The result is a simple yet effective showcase of integrating multiple data sources and rendering text within an SVG-enabled page.

Live API coding for fame

This example demonstrates live API coding for fame, fetching parking location data from the RDW Open Data endpoint (`https://opendata.rdw.nl/resource/t5pc-eb34.json`) and logging it to the console. It retrieves all records, then uses custom filtering and utility functions to extract and analyze values from the `areaid` and `usageid` columns. The code highlights unique values in those columns and counts empty strings in area IDs, showing how to programmatically explore a public dataset through JavaScript's `fetch` and JSON handling.
