Generation and adaptation of a visualization from one or more data sets without pre-building and storing the visualization prior to receiving a request for the visualization

A system comprising:

• at least one controller, which includes code running on a processor connected to memory, the controller configured to:
• analyze one or more data sets in their entirety, wherein the at least one controller is further configured to:
• retrieve schema and meta-data information of the one or more data sets, and
• generate heatmap information based on the retrieved schema and meta-data information, the heatmap information indicating a relative importance level of data tables and data fields within the one or more data sets,
• store the meta-data information and the heatmap information,
• create indexes to group and store data from the one or more data sets,
• import data from the one or more data sets into the created indexes, using the stored meta-data information,
• receive, from a user, a first request for a first data visualization, and
• in response to receiving the first request, automatically generate the first data visualization in real-time without the first data visualization being pre-built and stored prior to receiving the first request, wherein the at least one controller is further configured to:
• determine a format for the first data visualization based at least partially on the meta-data information, the heatmap information, the indexes, and data values that are relevant to the first data visualization, and
• fetch the data values from the indexes that are relevant to the first data visualization;
• and
• a display communicatively coupled to the at least one controller, the display configured to display the generated first data visualization to the user.
