Instead of

    var data = [
                {"set":["A"],"name":"node_0"},
                {"set":["B"],"name":"node_1"},
                {"set":["B","A"],"name":"node_2"},
                {"set":["B","A"],"name":"node_3"}
                ]

We use

    var data = [
                {"set":["A"],"name":"node_0"},
                {"set":["B"],"name":"node_1"},
                {"set":["C"],"name":"node_2"},
                {"set":["B","A","C"],"name":"node_3"}
                ]

we Get

WARNING: area A,B,C not represented on screen

Experimenting, I can never get nodes that are member of more than two sets to work

If I use the following data set, I would expect two circles with an overlap in the middle with one item in:

[
{"set":["A"],"name":"node_1"},
{"set":["A"],"name":"node_3"},
{"set":["A"],"name":"node_4"},
{"set":["B"],"name":"node_2"},
{"set":["A","B"],"name":"node_6"},
]

But instead I get

Is the data incorrect or is that how the plugin is intended to work?

Hello,

I've been playing with this repo and found some issues apart from #2 and #3, being the main one that it doesn't work out of the box with d3v4 because of the different namespace convention adopted. -d3.layout doesn't exist anymore-

Also I think in order for the community to benefit from your work it should be merged and maintained in the original venn.js. Obviously this is up to you but as I said I think it'd be beneficial for everybody.

I've opened another issue there in case you want to join the discussion:
benfred/venn.js#88

I'm having trouble using this module – I added venn.js as a dependency, but I'm getting a compile error there because:

ParseError: 'import' and 'export' may appear only with 'sourceType: module'

which I believe you tried to fix in your PR over there.

If I want to use your module, what should I do?

The simple and interactive examples are throwing

TypeError: d3.layout.venn(...).size(...).value is not a function

exception.
