In the scope of this BSc thesis, we described the problem of data visualization, which due to the amount of data or the complexity of graphs often does not show its full potential. We mainly focused on production company data, because there are a lot of Manufacturing Execution Systems (MES), which provide us the overlook on our production. We have presented three tools that can be connected and use them to create our own data visualization system. We have described in detail ArangoDB database and storing of the data. We also described a programming interface called Node-RED, where we built the core of the system for communication between Grafana and the database. In the end, we showed the finished visualization system and all the graphs made in Grafana. We presented line and table graphs, some extensions to diversify individual graphs, and the basic and advanced functions that Grafana offers to the user. In system development, we presented the meaningfulness of using Grafana and why it is one of the best choices for data visualization.
