so true. I think this is one of the downsides of d3 being so prolific in the past. all examples on Observable are up-to-date, so searching on here could be useful: https://observablehq.com https://observablehq.com and if you find a bl.ock that you really want to port, this changelog could be helpful: https://github.com/d3/d3/blob/master/CHANGES.md#changes-in-d3-40 https://github.com/d3/d3/blob/master/CHANGES.md#changes-in-d... most of the changes are simple name changes that put the methods directly on `d3`: eg. from `d3.scale.linear()` to `d3.scaleLinear()`
