marksVizQL

marksVizQL is a visual query language developed by Tableau Software. It is the underlying language that translates user interactions within Tableau's drag-and-drop interface into executable queries against data sources. Instead of writing SQL or other query languages directly, users build visualizations by dragging and dropping fields onto shelves such as columns, rows, and marks. marksVizQL then interprets these actions to construct the appropriate data requests.

The primary goal of marksVizQL is to abstract away the complexities of data querying and manipulation, making data analysis accessible to a wider audience. It allows users to rapidly explore data and create visual representations of insights. When a user builds a visualization, marksVizQL generates a representation of that visualization that can then be translated into queries for the connected data source. This can include filters, aggregations, and joins. The efficiency of marksVizQL contributes to Tableau's ability to provide a responsive and interactive user experience, even with large datasets.
