comment Create interactive map with no server
The common mistake with TopoJSON is to not look inside the JSON and understand it's structure when using it with D3. If you copy the example code and replace the their TopoJSON with yours you need to make sure that objects referenced in the TopoJSON actually exist in your JSON also.

All of them ;-) Although anywhere in the EC contributing to INSPIRE will be singled out for special attention!

comment What does Scale mean in the reference of Desktop GIS or WebGIS?
Just to add to that, remember that most web maps are using Web Mercator which obviously causes extreme distortions at the poles therefore the scale bar on most web maps is adjusted to show the scale at the centre of the current view rather than anywhere that you can see on the map.

comment How to publish maps to web with no programming required?
MangoMap only uses shapefiles to accept the data, under the hood it's using PostgeSQL/PosGIS. I've seen the global tree hight data loaded into it so it's capable of handling absolutely massive datasets.

comment Is it possible to show migration arrows on Leaflet map?
Yes a polygon or a line. I would probably go with a line as a polygon will might not look so good at all zoom levels. Whilst a line the thickness will the same at all zoom levels. Do a Google image search for "whether map" you'll probably get some good inspiration there.
