InfluxDB is an open-source time series database optimized for fast and highly available data storage, while Grafana is a popular data visualization and monitoring platform used to create dashboards and visualize data from various sources. The combination of InfluxDB as the data store and Grafana for visualization enables users to efficiently query and display their time series data. To set up this combination, users can install Docker Desktop, navigate to a specific directory, run a script, and start the containers using `docker-compose`. After setting up credentials, connecting Grafana to InfluxDB is achieved by adding a data source in the Grafana UI. Users can then create their first Flux query using Grafana Explorer, visualize financial data with more advanced queries, and create dashboards to display their time series data. Additionally, users can import CSV files into InfluxDB, use Flux to perform advanced manipulation and transformation of data, join data from multiple sources, and enrich time series data with metadata from relational databases or other sources.
