This a visualizer for the Litecoin Lightning Network. It can apply to mainnet or testnet depending what mode LND is running under.
Lightning-viz supports advanced node querying (enter query: into the search bar) and remapping of the graph based on the node search results.
The server also periodically pings peers to determine their connectivity. The server collects geo-location data on nodes that have an address configured.
lightning-viz requires LND 0.4.0-beta to be installed locally.
