## Old data format
|
||||
|
||||
If you want to still use the old [ffmap-d3](https://github.com/ffnord/ffmap-d3)
|
||||
front end, you can use the file `ffmap-d3.jq` to convert the new output to the
|
||||
old one:
|
||||
|
||||
```
|
||||
jq -n -f ffmap-d3.jq \
|
||||
--argfile nodes nodedb/nodes.json \
|
||||
--argfile graph nodedb/graph.json \
|
||||
> nodedb/ffmap-d3.json
|
||||
```
|
||||
|
||||
Then point your ffmap-d3 instance to the `ffmap-d3.json` file.
