Charts that can be used anywhere

A chart is simply defined by its URL, so you can use our chart API in any programming language you like. And because our API produces images, you can include these charts nearly anywhere.

We support many languages and frameworks, including Python, Javascript/Node, Java, C#, and PHP.
