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.
If it's small as in the couple-of-MB range you could convert to GeoJSON, serve it as a static file fed into a small web app like u/techmavengeospatial suggested that handles filtering by query, and update the file as new data comes in. Alternatively if you want something more robust you can feed it into PostgreSQL and serve with something like pg_tileserv (with equivalent filtering in the web client).
