You can see the visualization by uploading output.json via the UPLOAD button.

output.json, one of the SimBlock's output files, is listing occurred events during a simulation.
If no files have been uploaded yet, this visualizer displays the visualization for the default output file as a demonstration.
Note: This visualizer supports only the default setting for a list of regions ― BlockChainSimulator.settings.NetworkConfiguration#REGION_LIST.

The correspondence of each visible object is as follows:

Circle: a blockchain node.
- The coordinates (latitude and longitude) are randomly determined around the region of the node.
- The color is associated with the latest block of the node.
- Large circle: a miner of the block corresponding to the color.
Edge: a propagation from a node to another node at the timestamp.
- The color is associated with the flowing block.
- Bold edge: a propagation just received at the timestamp.

Draw each propagation not only at the timestamp of the block reception, but between the transmission and the reception.
