You could probably create a widget object that implemented the following methods and the rest of the widget would work:

widget.openURL(url) – could be implemented as window.location = url;
widget.setPreferenceForKey(key, value)
widget.preferenceForKey(key)

That said, implementing that API may be quite challenging due to the need to store preferences on a server somewhere. Additionally, there is the challenge of cross-site XMLHTTPRequests for fetching station data. As well, since web-pages are generally reloaded often (unlike dashboard widgets), there isn’t the need for the dynamic refreshing of the graph.

Were I to make this into a plugin for WordPress or Drupal where the site administrator is choosing the station, I’d probably rewrite the whole thing in PHP and just display a static <img src='http://....'/> tag for the selected station. If you pursue this, good luck! I’d love to hear how it turns out.

I am wondering if you’d be interested in modifying your widget code for use in various CMS’s like WordPress and Drupal? If you’re not interested or don’t have the time, might you have some suggestions on how to go about it?
