如何根据文档说明在.edges(Array | Object | url)方法中使用Object,将箭头方向更改为目标从源到目标. D3plus Documentation.
完整代码如下以了解箭头方向.

<!doctype html>
<meta charset="utf-8">
<script src="//d3plus.org/js/d3.js"></script>
<script src="//d3plus.org/js/d3plus.js"></script>
<div id="viz"></div>
<script>
  var connections = [
{"source": "alpha", "target": "beta"},
{"source": "alpha", "target": "gamma"},
{"source": "alpha", "target": "delta"},
{"source": "alpha", "target": "epsilon"},
{"source": "alpha", "target": "peta"},
{"source": "alpha", "target": "zeta"},
{"source": "alpha", "target": "eta"}
  ]
var visualization = d3plus.viz()
    .container("#viz")  
    .type("rings")      
    .edges(connections) 
    .edges({"direction":{"accepted":["source","target"],"value":"source"}})
    //.adeges({"direction":{"accepted":["source","target"],"value":"target"}})
    .edges({"arrows":true,"color":"#000000"})
    .focus("alpha")     
    .draw()
</script>

解决方法:

试试这个：

<!doctype html>
<meta charset="utf-8">
<script src="//d3plus.org/js/d3.js"></script>
<script src="//d3plus.org/js/d3plus.js"></script>
<div id="viz"></div>
<script>
    var connections = [
        {"source": "alpha", "target": "beta"},
        {"source": "alpha", "target": "gamma"},
        {"source": "alpha", "target": "delta"},
        {"source": "alpha", "target": "epsilon"},
        {"source": "alpha", "target": "peta"},
        {"source": "alpha", "target": "zeta"},
        {"source": "alpha", "target": "eta"}
    ]
    var visualization = d3plus.viz()
    .container("#viz")  
    .type("rings")      
    .edges(connections) 
    .edges({"arrows":true, "color":"#000000"})
    .edges({"arrows": { "value": ["source","target"], "direction": "source"}})
    .focus("alpha")     
    .draw()
</script>
