Hi Vlad,

Very nice case for interactivity in the charts! I have written a tip in a similar vein on the amCharts blog here https://www.amcharts.com/dataviz-tip-23-use-interactivity-to-avoid-overwhelming-viewers-with-excessive-data/

We at amCharts got inspired by your blog post and decided to recreate your demo using amCharts v4. In addition to the same level of interactivity, you get the ability to move the nodes and switch them off and on. Check it out here:
