Visualize Group by result

Hi Afharo,
Thank you for your response, Yes I want to create a dashboard where I want two visualizations

  1. Histogram
  2. Percentiles Graph
    But for each visualization, I want to group by my data based on 10 categorical columns region, country, city, usage_cat etc, after grouping the data, I want to pick the 2 groups with the highest count and want a grouped histogram for these 2 groups data.
    Similarly for percentiles, after picking 2 highest count groups I want to show the percentile difference between these two groups
