Animations Along Lines
amCharts Map Chart has all the tools you need to connect points on a map taking the geography and geometry into account. And then you can even animate objects along those connecting lines.
Key implementation details
We create MapLineSeries to represent our lines. We set it up by providing pointsToConnect. Then we create MapPointSeries to represent the position of our plane. We set it up by setting lineDataItem to our map line series and then we animate positionOnLine.
