How to display big interactive map(or html) in PyQt6

Question

Current situation :

Polygon data was placed on top of the folium map. And I'm trying to display the map in pyqt6. However, it is not applicable when the data becomes large. Because "html_string" has a limit for 2MB.

       geojson_data = gdf.to_json()
        folium.GeoJson(geojson_data,
                       style_function=lambda x: {
                           'color': color_mapping.get(x['properties']['prt_type_nm'], 'gray')
                           }).add_to(m)

   
        html_string = m.get_root().render()
        self.web_view.setHtml(html_string)

Here is source code :

Tryed:

An error also occurs when saving html and loading it with an absolute path.

Ultimately:

Ultimately, what I want is for the data to be displayed in real time as values are selected in the sidebar. So, I don't think it's a good option for me in terms of loading.

Please help in other ways.
