* `basedOn` can be:
|
* 'value':
|
* This layout is not accurate and have same bad case. For example,
|
* if the min value is very smaller than the max value, the nodes
|
* with the min value probably overlap even though there is enough
|
* space to layout them. So we only use this approach in the as the
|
* init layout of the force layout.
|
* FIXME
|
* Probably we do not need this method any more but use
|
* `basedOn: 'symbolSize'` in force layout if
|
* delay its init operations to GraphView.
|
* 'symbolSize':
|
* This approach work only if all of the symbol size calculated.
|
* That is, the progressive rendering is not applied to graph.
|
* FIXME
|
* If progressive rendering is applied to graph some day,
|
* probably we have to use `basedOn: 'value'`.
