I tried to write the netjsongraph layout with SigmaJS, plus the previous
Echarts library, which has four effects:
- https://kutugu.github.io/NetJSONDemo/examples/netjson.html
- https://kutugu.github.io/NetJSONDemo/examples/netjson-sigma.html
- https://kutugu.github.io/NetJSONDemo/examples/netjson-bigData.html
- https://kutugu.github.io/NetJSONDemo/examples/netjson-sigma-bigData.html
Below I list some of the differences between the two libraries:
- Echarts：
- Advantage: Easy to get started. Support multi-function widget
extension (Node element classification, different theme, like day-night
mode in mesh viewer
<https://regensburg.freifunk.net/meshviewer/#/en/graph#!/en/map>)
- Disadvantage:
1.It is not easy to customize the extension, and there
may be some difficulties in encapsulating the deeper and later optimization
(need to modify the source code).
2.The parameters of the force algorithm is less, some of
which have to remove.
3. The node Label is always displayed. Big data may be
messy.
- Sigma：
- Advantage: Some optimizations can be made easily When big data
are rendered. Built-in features such as canvas scaling and panning, etc.,
and provide a number of plugins
<https://github.com/2XL/CN_Deliver2/tree/master/demo/linkurious/plugins>
for different functions.
- Disadvantage:
1. Features require a lot of plugins, less tutorials,
difficult to get started.
2. There are some problems in the handling of the drag
event, such as the dragging of the edge and the node will not maintain the
final position after dragging. The force layout must be stopped when
dragging.
3. Under WebGL accelerated rendering, some features are
not supported, such as edge's mouse events.
