Are u looking for a Javascript project? Why not consider creating dashboards for Data Analytics. Sales and Marketing departments worldwide use bar charts all the time. This one is created using Plain Javascript with no chart libraries. It presents some Javascript coding challenges. Try it out, fully commented code available from my codepen.
I wrote a Dev article on this topic at https://dev.to/rickdelpo1/how-to-populate-a-stacked-bar-chart-in-plain-javascript-12p9 click here for project details and my codepen.

A quick note about me. I am a retired Data Analyst wanting to contribute to the greater good of the learning community. All my stuff is free as I do this just as a hobby to keep my mind sharp at my age.
