• Usage

To install and run the D3 Tree locally, first install IPFS. Then:

ipfs daemon
# Open a new terminal window
git clone https://github.com/mohitkh/ipfsDagVis.git
cd ipfsDagVis/webapps/tree-ltr
make

Inside ipfsDagVis/webapps/tree-ltr run 'ipfs add -r . ' Now get the hash corresponding to 'ipfsDagVis/webapps/tree-ltr' folder. Lets say it is hash1.

Next, we need to add a folder/directory to ipfs. For that run the command 'ipfs add -r -folder_name' This folder gets added to ipfs and a hash is generated for each chunk. Lets say hash for root folder -folder_name is hash2.

To visualize this folder content in d3, open http://localhost:8080/ipfs/hash1/viz#hash2
eg. http://localhost:8080/ipfs/QmPK8rJ5iTYmiMrkm5MXjeqBg3TXZUMQcdyyuoPPZFMTJn/viz#QmXVrwyX5AUx5kWx3e9m49NuKAj57HJYmKbbRvHWMXbUQU in your browser
Change the IPFS hash at the end of the URL to see any other IPFS tree.
The first hash is the hash for 'ipfsDagVis/webapps/tree-ltr' folder in ipfs; the second hash is whatever is being visualized.

ipfs cat Qmcd7Sebd46vxDWjbUERK8w82zp8sgWTtHT5c93kzr2v3M >/usr/local/bin/grapher
chmod +x /usr/local/bin/grapher

grapher hash2 | dot -Tsvg >graph.svg
grapher hash2 | dot -Tpdf >graph.pdf
grapher hash2 | dot -Tpng >graph.png

eg.
grapher QmRCJXG7HSmprrYwDrK1GctXHgbV7EYpVcJPQPwevoQuqF | dot -Tsvg >graph.svg
grapher QmRCJXG7HSmprrYwDrK1GctXHgbV7EYpVcJPQPwevoQuqF | dot -Tpdf >graph.pdf
grapher QmRCJXG7HSmprrYwDrK1GctXHgbV7EYpVcJPQPwevoQuqF | dot -Tpng >graph.png

The above lines will generate Merkel DAG in svg, pdf and png format.
The hash2 used is the hash of the folder/data to be visualized
