Visualisation selector

**Goal** As a user of, I want to be able to identify and select the right visualisation in order to effectively visualise my data and get insights. **Requirements & Caveats** From usability research we have seen that first time user are having difficulties to identify the visualisation selector and understand how and which visualisation should choose for their data. Default viz is a timeseries but it is tricky for users to navigate to the corresponding selectors and browse other types as well. This is a quick win effort and we should explore solutions that can be conceptualised fast. That would mean to explore solutions on top of existing architecture or layout. Possible routes would be to have the visualisation list expanded by default or explore more user friendly descriptions or auxiliary text. ```[tasklist] ### Tasks - [ ] https://github.com/grafana/grafana/issues/66459 ``` **Design** Figma file **Docs** [Product DNA](https://docs.google.com/document/d/1jbqxur2WiFtUf71YJFPg-TFpQyvlD2ol2cMq-I1aKyI/edit?usp=sharing) [Figma Wireframes](https://www.figma.com/file/jE9lC14QMCiJ870TuCDfWg/Dashboards-Wireframes-and-Exploration?node-id=250%3A6413&t=0pRxWgHHGeD8lj32-1)
