Abstract: Dashboard evaluation includes receiving a dashboard code defining a dashboard that includes visualizations in a layout, rendering, in a graphical user interface (GUI) of a dashboard editing tool, the dashboard based on the dashboard code, and extracting, using the dashboard code, a data attribute of a data object represented by a visualization of the multiple visualizations. Dashboard evaluation further includes evaluating, by the dashboard editing tool, the visualization based on the data attribute to obtain a score, presenting, in the GUI of the dashboard editing tool, a recommendation based on the score failing to satisfy a first threshold, receiving, through the GUI of the dashboard editing tool and after presenting the recommendation, an edit to the dashboard code that adjusts the visualization, and storing, by the dashboard editing tool, the edit to the dashboard code.
