Duplicate nodes?

[Sabre36]

This is very nice visualization for showing a flow diagram. However, I'm not sure if this is by design or possibly a bug, but when a node that shares a link a sibling node, a duplicate/orphan node is created (instead of just the Sankey funnel pointing to the shared node). Consider this code:

    const nodes = {
        0: {
            title: 'Col 1',
            value: 20,
            id: '0'
        },
        1: {
            title: 'Col 2.1',
            value: 10,
            id: '1'
        },
        2: {
            title: 'Col 2.2',
            value: 15,
            id: '2'
        },
        3: {
            title: 'Col 3.1',
            value: 5,
            id: '3'
        },
        4: {
            title: 'Col 3.2',
            value: 5,
            id: '4'
        }
    };

    const links = [
        { sourceId: 0, targetId: 1 },
        { sourceId: 0, targetId: 2 },
        { sourceId: 1, targetId: 3 },
        { sourceId: 2, targetId: 3 },
        { sourceId: 2, targetId: 4 },
    ];

I would expect that { sourceId: 2, targetId: 4 } would point to the shared node 4 (it does so correctly). But, there is also an additional node 4 that is now an orphan.

Is there a way I can eliminate the extra node and just have shared links? Thank you in advance.

Hello, sorry for the late response. I didn't consider that case when a node can be shared between two or more parent nodes. In such case, it will calculate links incorrectly.
