Take a look at QGraphicsView framework, https://doc.qt.io/qt-6/graphicsview.html it's one of the most powerful graphics frameworks I've used. In addition to scene-to-object transformations (with object hierarchies) it gives you many powerful tools to render complex, interactive scenes.
Alas, I have not found a web equivalent that works as well as QGVF.
