Loading data through SPARQL
This example demonstrates a SPARQL query against the Network of Digital Heritage (NDE) API, displaying the results as raw JSON text in a paragraph element. The visualization shows counts of cultural heritage objects grouped by material type and African place names. The code uses D3 v5’s `d3.json()` helper to fetch data from the SPARQL endpoint, with the query wrapped in template literals and passed as a URL-encoded parameter. The results are rendered by directly setting the innerText of the paragraph, without any further visual encoding.
