Cursors themselves do not directly improve performance in the context of programming or data processing. Instead, they are used to manage the interaction between the user and the graphical interface, particularly in visualizations.
In the example provided, cursors are used to enhance user experience by indicating different states or actions when hovering over different parts of a plot. This can make it easier for users to understand what they are interacting with, but it does not inherently improve the performance of the underlying model or data processing tasks.
If you have a specific context or application in mind regarding cursors and performance, please provide more details!
