Getting started - trying a really simple graphical example with a simple number from cURL

Hello,

I stumbled upon Grafana and it’s a great product. While I love all the ways to injest from various sources such as Elasticsearch, I’m looking to generate some PoC’s for Upper Management from some data points that I have developed from some internal scripts. As an example, https://foo.com/variable returns a simple number that I’m looking to graph over time.

Apologies if I overlooked this - I did read a few of the data input documentation pieces but I didn’t see a basic example that I could get started with.

Thank you
