Allow LLM to further customize widgets

[bklieger-groq]

Currently, the LLM utilizes function calling to render specific widgets. For some widgets, such as charting, a stock is specified. Others like screener have no input.

It would be great if the LLM could also customize specific aspects of the widgets.

As an example, the chart widget could have an optional "Bar's Style" parameter in the function call.

As a user, if I ask for a bar chart, I get a bar chart. If I ask for a Heikin Ashi chart, I get a Heikin Ashi chart. If I ask for an area chart, I will get the correct chart.

To accomplish this feature, a new parameter would need to be added to the widget alongside updated documentation. The function-calling agent would need the capability to accurately specify the chart type as part of the function call and have a default if no match is found (the default functionality could be validation that happens as part of the function). The caption agent would need to know which chart type was rendered.
