I’m working on a website that sells travel tours. For each tour, I want to display a map with the various stops. I chose to use polylines to “join” each city following the roads on the map but drawing them one by one is very tedious and time consuming. It requires a lot of zooming in and out and quite often, when I zoom out enough to see which road I should follow I end up clicking on the previous point so the polyline stops extending. The only way to extend this line is to grab that last point and move it to the end goal. Finally I create more points by drag and drops to the needed position. But still, this is slow and not precise.

On Google Maps we enter all the destinations then grab the lines and drop them on the road we want. It’s super fast. I’m not sure if APIs maps offer this behavior for free and/or if it’s technically something too hard to introduce but then, how about curves ?

Joining those cities with straight lines does not look great at all. It would be great if we could create curves instead of straight lines. On software like Affinity or the default note tool in Finder (MacOS) we can draw a line and then grab it any where in the middle to create a curve. Having curves would give more possibilities in term of presentation.
