Sometimes, Holistics' default visualization types may not be enough for your business needs. You may want to use charts that we do not support yet, or create a more customized chart type with modifications specific to your organization. The Custom Chart feature is, therefore, introduced to help you create custom, reusable chart templates that accommodate your needs.

Custom Charts are user-defined chart templates written using Holistics and Vega-lite syntax. Once created, it is available to everyone in your organization to use. The creation of a Custom Chart typically follows these steps:
- An Admin creates the chart definition.
- Other users within the organization can select the new chart type to build reports.
