Clarification about InfluxDB V2 and Telegraf

From various images and videos I got the impression that InfluxDB V2 (alpha) already implements a kind of dashboard designer just like Grafana does.

If so, does this mean I do not need Grafana anymore, at least when solely using InfluxDB as a data source?

Again from videos: I saw that I can configure Telegraf right from within InfluxDB V2. Is this correct? This implies to have Telegraf running on the same host. What about if I run Telegraf on a different host w/o InfluxDB?
