noita-map-viewer VS qgis2web

MAJOR SPOILER WARNING: Start grabbing those orbs!

no problem. here's an interactive map of the world so you can see what's under the desert. there's spoilers though, obviously

Here's the world map if you are interested - HUGE spoilers, obviously.

If rng is on your side you can go really far to either left or right of the starting area and theres like... 3 times as much content as in the "Main path" down. Ill link a map of the entire noita biomes, but the map changes based on seed since its semi randomly generated and youll be able to see the "main" cave path down and then the desert with the pyramid to the right and more stuff to the left. https://noita.datahoarder.dev/

There is qgis-server but if the content is static you can probably get by with https://plugins.qgis.org/plugins/qgis2web/

There's a QGIS plugin qgis2web that will take your QGIS project and create an HTML file out of it. I've used it once or twice and there were a couple of issues but I can't tell whether it's due to the plugin or my ignorance.

I think the easy option might be qgis2web plugin. Not quite sure it works exactly, but my understanding is it really simplifies the development process. Might be worth having a look https://github.com/tomchadwin/qgis2web

If you already / Once have your squares with data, then it's only displaying them on a map. QGIS2Web, Openlayers, Mapbox or CARTO can be some ways to start but if you want user interaction you'll probably have to code it yourself. Bokeh can probably be used for that too (Mapping geo data) but you'll probably have less liberty than in JS.

I suggest you start your research by looking into qgis2web (https://plugins.qgis.org/plugins/qgis2web/). Load your data into qgis, hit the qgis2web button, you'll have that map as a webpage.
