i get empty graphs and i dont know the reasons for this. may the data types or something else likw the code itself.
type string
director string
country string
rating string
Create a RadioButtonGroup widget called graph
` graph = pn.widgets.RadioButtonGroup(name='Y axis', options=['rating',], button_type='success')
Create a new pipeline
graph_pipeline = ( idf[ (idf.country.isin(checkbox_group))] .groupby(['type'])[graph].nunique() .to_frame() .reset_index() .sort_values(by=['type']) .reset_index(drop=True))
Create a visualization interactive using hvplot
graph_plot = graph_pipeline.hvplot( x= 'rating', y=graph, line_width=2, title="Test", width=800, height=400, legend='top' ) graph_plot`
