Enterprise-tier example: live-data dashboard — NWS API / open data + D3/Chart.js on managed DB; pre-2010 demanded a custom build

Claim: A live-data product / dashboard — e.g., a public-facing status or metrics dashboard pulling a live feed (NWS/NOAA api.weather.gov — free public REST/JSON API, no key, no registration, no rate-limit account, a government open dataset, or the business's own RDS data) rendered with D3.js released 2011 by Mike Bostock (with Heer & Ogievetsky, Stanford) — foundational data-viz building block or Chart.js (MIT, free) and Highcharts (free non-commercial, ~$590+ commercial) — higher-level charting layer. Pre-2010 this demanded a custom build at every layer.

Source: Synthesis of the parts + data entries.

Confidence: Industry-consensus.

Why this matters for Candid: Second canonical worked example. Useful in conversations with SMBs whose pitch deck implies "we need a live dashboard" — the components are now free or near-free, the integration work is the real spend.
