As I design my webpage, I plan to include several circles with onmouseover effects (tooltip pop-ups). However, I am concerned that many visitors may overlook this feature. I am curious to know what strategies you typically employ to capture visitors' attention and emphasize the presence of an onmouseover effect.
Edit: Just to clarify, my question is "How can I effectively communicate to visitors that there is a tooltip effect available on an element?"
Thank you in advance for your recommendations!
