uMap
uMap lets you create maps with OpenStreetMap layers in a minute and embed them in your site. (by umap-project)

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.
For public display one of the uMap instances is probably easiest. It should allow you to import your previously exported points and also allows line and area attributes. The share link included embed code for a website. The instance linked by /u/beardy64 is probably the most popular, but there are several listed at my previous link. I would recommend you log in before creating the maps as without a login you have to carefully keep track of you edit URL's if you might ever want to update things.
I like using http://share.mapbbcode.org for a similar purpose.
