A bar chart ranks the top 20 brands by the number of influencer collaborations, using a horizontal count of sponsored posts per sponsor. The visualization shows which brands appear most frequently in the influencer’s content, with higher counts indicating stronger collaboration presence. The code builds a Pandas DataFrame by extracting sponsor handles from a pre-existing `sponsored_df`, then groups and sorts the data before plotting with Plotly Express’s `px.bar`. Engagement rates are recorded alongside each sponsor, though the final chart displays only the frequency counts, not the engagement values.
