  • Publication number: 20250371019
    Abstract: Techniques are disclosed relating to automating data visualization using machine learning. In some embodiments, a computer system receives a request for program instructions to render a graphical chart from data stored in a database of the computing system. The request includes an image of a desired graphical chart. The computer system applies a machine learning model to the image to determine one or more query parameters associated with the desired graphical chart. The computer system provides the requested program instructions to render the graphical chart. The requested program instructions include a database query specifying one or more query parameters to retrieve the data from the database. The computer system may render the graphical chart based on the provided program instructions.

  • Publication number: 20250348489
    Abstract: Latency, response times, and efficiency improvements for data querying are provided herein, particularly in the context of querying large database systems and data tables from disparate data sources. There are provided systems and methods for automatic query and data retrieval optimization through procedural generation of data tables from query patterns. A service provider may utilize different computing services for query processing and data retrieval for different applications and services used by internal and/or external users. Instead of querying large database systems and numerous data tables, pre-aggregated data tables may instead be used and searched by procedurally generating such tables based on precomputation rules and query patterns. Once patterns have been identified in queries, corresponding data may be aggregated from data sources in a pre-aggregated data table. Query optimization rules may then be used to have these data tables queried in place of their original sources.
