Live Gold Price & Silver Price Charts Widgets

The plugin does exactly what it offers.

Yet, in my opinion, it is poorly implemented. The plugin merely includes iframe code from www.goldbroker.com instead of directly fetching the prices from an API and displaying it itself (without an iframe). 
(The same functionality could be achieved by copying the iframe code (with the url and the needed parameters) and pasting it into a text widget.)

Works, but bad implementation
