Create dynamic charts

Hi all,

I need to implement a dashboard that will present several bar charts based on the number of rows returned in my dataset. As illustration, my dataset is like below:

Category             KPI           Value

CAT1                   KPI A        10

CAT1                   KPI B         5

CAT2                   KPI C         3

CAT3                   KPI D         8

CAT3                   KPI E          1

CAT3                   KPI F          10

CAT3                   KPI G          9

The slicer will contain the list of categories (CAT1, CAT2, CAT3). If the user selects the CAT1 on the slicer, then my dashboard needs to present 2 diferent bar charts for KPI A and KPI B. If the user selects CAT3 then the dashboard will present 4 diferent bar charts.

How to implement that? Do I need to create a custom visual? If so, is there any example to guide me?

Thanks a lot,
