i believe kobo data visualization is not enough for enterprise demand i suggest use other tools like tabelau or excel
As mentioned by @Yonatan normally the visualization provided may not be suited to provide all the visualizations need of each and every user. Some advanced level of customizations and data visualization needs are best addressed by other tools which may not necessarily be within the scope of what KoBoToolBox can support.
