I think this means producing complete HTML that does not need embedding anywhere else.

Hi @astrojuanlu! Is there currently any good way to use the CZMLWidget HTML representation outside of a notebook, e.g. embedded within some template page?

Hi @lalligagger! If I recall correctly, this widget does not (yet) have any jupyter-specific code, it's just a blob of HTML. The only thing missing is <html>, <head>, and <body>, but maybe this is perfect for what you need.

Have a look at the to_html method:

czml3/src/czml3/widget.py

Lines 97 to 103 in 46b4342

def to_html(self, widget_height="400px"):
return CESIUM_TPL.format(
cesium_version=self.cesium_version,
script=self.build_script(),
container_id=self._container_id,
widget_height=widget_height,
)

Ok, I haven't been able to get standalone html working but a mashup of the extractor and the approach taken below has me running in a dash app!

What exactly didn't work, or what errors did you observe? Would be useful to know so we can try to address them.

I added your suggested tags to beginning/ end of to_html output and saved as .html but nothing renders in that case.

The existing "to_html" function actually works, but you need to load RequireJS in the html page you want to hold the resulting widget. For example:

from czml3.examples import simple
from czml3.widget import CZMLWidget

view = CZMLWidget(simple)
html = view.to_html()
page = f"""<!DOCTYPE html>
        <html>
            <head>
                <script src="http://requirejs.org/docs/release/2.3.6/comments/require.js"></script>
            </head>
            <body>

            <!-- CZMLWidget -->
            {html}

            </body>
        </html>
        """

# save to file
with open("CesiumJS.html", "w") as file:
        file.write(page)
