Add a background map for sigma js - background

I have created a graph in Gephi using GeoLayout (showing network over the world). Now for my visualization I would like to add a background map in sigma.js ideally something like openstreetmap or a similar service. Is that possible?
Otherwise I could also imagining adding the graph to a leaflet map if that is easier. In any case I would need to know how this can be achieved. Any help is appreciated. Thanks!

How to generate custom template for sharing contents in instagram stories

I'm working on a React Native app, and I'd like to create a function for sharing contents in Instagram stories, like the tweet below.
How can I generate a custom template, like Twitter does, using Python? Because my backend is written in Django.
=== UPDATE ===
I have done some research and found out that you can use various languages, such as FabricJs or PIL in Python, to draw an image. However, these can be a nightmare for high-complexity stickers. Therefore, my solution is to simply take a screenshot in the app using react-native-view-shot.
If someone has any better solutions, they would be greatly appreciated.
Thank you.
Websites previews based on website meta tags like open graph
You can use this library to generate it https://github.com/tjcages/expo-link-preview.
However, it maybe a better solution is to build these previous on the backend like here https://github.blog/2021-06-22-framework-building-open-graph-images/
And then share image with https://github.com/react-native-share/react-native-share

Is there any package to show highlighted vector maps in VueJS?

I want to implement a map like this:-
in which vector layers of countries are highlighted according to some metric value. I tried to search for some package but found JQuery based JQVMaps and jvectormap, which I want to avoid to use since my framework is VueJS.
Can someone suggest some package for this? Or should I go for integrating these Jquery based packages itself?
Leaflet is great and simple to learn library to work with maps. Fortunately there is a wrapper called vue2-leaflet that make it work with Vue. Regarding your Image this part of docs may useful for you.

See the result of a query on the map with Arcgis Api JS

Let's say you enter these parameters. Which method of the "ArcGISImageServiceLayer" class can serve to display the image of the mosaic dataset? In the attached image the result is an image, but I do not know how to visualize it on the map.
Part of my code is this, I used the "queryVisibleRasters" method to try to visualize it, but it did not work, any suggestions are very well received, thanks

Draw connections/paths between elements in XAML

I am currently developing an app where you can move different elements (boxes) and I need to display several arrows between them to show off connections and data flows. I don't want to use simple lines because this looks crappy. I recently used this great JavaScript library which does the thing I need for HTML: http://jsplumbtoolkit.com/jquery/demo.html
Is there something similar for XAML out there?
Thanks in advance!
I think, you should use bezie curves. From MSDN
To create a quadratic Bezier curve, use the PathGeometry, PathFigure, and QuadraticBezierSegment classes.

How do I make legends in Google Maps with a Google Fusion Tables Layer work?

i am using Google Fusion Tables and Google Maps to display geographical data (e.g. markers). My map needs to have a legend, for example by inserting a div on top of the map and the layer. As i am not used to work with API of any kind, i got stuck with this legend problem.
I tried several example codes (most of them provided by google), but none worked for me. I guess that the problem of displaying divs on a map has got something to do with either the styling of the map canvas, the div implementation within the body of the html document or with the framework used (google appengine). But this is just guessing. As i am not a professional with coding, i maybe missed a important point. Maybe the folks here can help me out?
Every hint is appreciated. Thanks.
You can have a look at the code and my example [here (deleted)]. There example includes a code which should display a div, but it doesn't. I've taken it from here (Stackoverflow).
The code you're using is v2 of the Maps API. You'll want to use code that works with v3 of the Maps API, since that is the version you're using on your site.
Have you tried the sample code here?
https://developers.google.com/fusiontables/docs/samples/legend
Copy and paste the legend code from this example into your initialize method, remove the old legend code. If this doesn't work, let me know.
