Dynamic Axis Scaling in Animated Charts

[philippulus]

Hi community,

I am looking for creating animated charts with dynamically scaling axis, changing X and Y values and moving symbols like in this example.

DynamicChart.mp4

Looking at this bar chart race example I get the impression it was made with d3js. Is this correct?

Here's a snippet that does dynamic ticks based on a specified density (ticks per pixel):

axisLeft(yScale).ticks(yTickDensity * (height - margin.bottom - margin.top))

Here's an old piece on bl.ocks.org that does this: https://bl.ocks.org/curran/6f97aa94357cae4611c54a80c11f6128
