What option is false about implementing custom visualization plugins in Oracle Analytics Cloud?

The assertion that custom plugins must be placed in the correct directory without requiring service restarts is misleading because, in practice, Oracle Analytics Cloud requires that changes to plugin files are followed by a service restart to properly load and register the new or updated plugins. This is an important part of maintaining the integrity and performance of the Oracle Analytics Cloud environment.

Each of the other statements is accurate. Custom plugins can indeed be created using the bicreateplugin script, which is intended to simplify the process of building plugins tailored to specific visualization needs. Additionally, Oracle provides a comprehensive Software Development Kit (SDK) that allows developers to create custom plugins while ensuring they follow Oracle's framework and standards. Furthermore, for users looking for advanced visualization techniques, the option to source plugins from the Oracle Data Visualization Library is available, enhancing the overall functionality and visual representation of data. Thus, the incorrect nature of the statement about service restarts establishes it as the false option in regard to implementing custom visualization plugins in Oracle Analytics Cloud.
