The thermometer chart was first published on
CodeProject on July 22, 2009 — a technical article showing how to generate a thermometer image
dynamically using ASP.NET and VB6, with all parameters passed as URL query strings so it
could be dropped into any page as a plain <img> tag. The jlion.com
builder launched the same year, letting anyone configure and embed their own thermometer
without touching code. That same approach — a single URL, no JavaScript required
— is still the foundation today.
Free thermometer in under a minute. No account needed.
