Large dataframe caused visualization to hang

[gongwork]

Is your feature request related to a problem? Please describe.
While building a demo using Vanna, I encountered an issue where the visualization step hanged for a large dataframe (e.g. 10k rows)

Describe the solution you'd like
Check the dataframe size, limit number of rows to be plotted.

Describe alternatives you've considered
I appended a limit clause in the generated SQL

Additional context
It is meaningless to plot a chart with too many data points
