InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I see. In that case, a good starting point is R4DS (as mentioned by /u/Enders_Ruin). That book also has a second version in the works, and a Slack channel to ask questions / discuss / find reading buddies.
For visualizations, you could follow/participate in TidyTuesday: a weekly "challenge" where you are given some data and plots to generate with that data. A lot of people participate, and most (if not all) post their code online. You can find most of them on Twitter with the #TidyTuesday hashtag. There's also the #30DayChartChallenge in the same vein. You can track some of the recurring participants' websites/github repositories to see their work & code (just to mention a few from the top of my head: Cedric Scherer, Lisa Debruine).
