I’ve developed a simple visualization using HTML/CSS/Javascript and D3 library locally and want to have it display on the homepage of my Omeka site. Currently, my homepage is a Simple Page (created using Simple Pages plugin) and I want to retain the theme and navigation bar but also add my custom HTML/Javascript, to display my visualization in the empty area beneath the nav bar.
Is there a way to include custom HTML/Javascript on a Simple Page? If not, is there a way to include custom HTML/Javascript on any page while retaining the selected Omeka theme, nav bar, and other elements I want to remain unaffected?
