Maybe use a "happier" example than COVID cases on your landing page? Something that people aren't depressed to see go up? Seeing a graph of COVID trending upwards is going to put potential users into a negative mindset immediately, not something you want when they are learning about your new product. It's definitely low-hanging fruit for "everyone knows what this is and why you might want metrics on it" but I'd try and come up with another example data set.
