Greetings,
I don’t see any graphs on that site but plenty of what I think are termed Steel Gauges.
I don’t use them, but know they have been part of WD’s offerings in the past.
I use a program called Meteotemplate which as one of it’s options, is a panel that shows steel gauge type indications.
See my link and look to the lower left near the bottom for Jachym’s implementation.
