水平显示D3网络图，不折叠

我正在创建一个网络图，它用路径连接节点。
我的要求很简单-网络图应该是垂直或水平的，没有折叠。
到目前为止，我创建了一个以水平格式显示图表的图形。
然而，如果节点集非常有限，则图形仅显示为单行（没有折叠）（我尝试了forceManyBody().strength()和forceLink(links).distance()的多次试错以使其工作）

但对于更大的不。图会这样折叠

d3.forceManyBody().strength(-600)的一些变体给我一个单行，但链接顺序相反，像这样--

在这里，5050圈应该是第一圈，但它在最后到来。
我的问题是
1.如何根据节点正确查找forceManyBody().strength()和forceLink(links).distance()，以便只有一行
1.为什么第一个圆圈最后才出现？
我不介意如果我必须滚动查看所有节点（可能是d3.zoom可以帮助？）
找人指点。请在下面找到代码和数据：

正如评论中提到的。您的用例非常简单，可以使用比例和形状重新创建。我使用了一个线性标度，并使用节点的索引作为标度的域，因为节点之间的时间间隔在多个数量级上不同。
每个节点包含在一个组中，以简化圆、文本和线的相对定位。
由于边的数量具有节点的长度-1，所以我使用each函数单独迭代节点组，并且如果当前索引不是最后一个，则仅附加边。
