feedback on the graph visualization

[percyliang]

Dimitris:

• it would be nice if different nodes had different sizes. Maybe datasets should be scaled by size or out-degree?
• i guess at a higher-level, maybe it would be worth thinking what takeaways we want from the graph (e.g., the disconnected components are cool) and then thinking about how to visualize them
• it would be nice to be able to quickly zoom in to specific assets, maybe a sidebar listing models/datasets (as tabs) where I can click on a model and visually jump to it’s neighborhood (I was trying to find the Pile and it took me a fat minute)
• it would be nice if you could isolate subgraphs: what lies downstream of the Pile?
• maybe it’s worth precomputing the graph arrangement? having things jump around was fun the first time, but annoying when I reloaded the page
• is there a way to initially display a coarse structure? maybe “PaLM and friends” so that i can take away something at a glance instead of having to parse the entire graph?

Ansh:

• Seems like the canvas size has a fixed height of 600, it looks particularly small on bigger screens. This should be a percentage value.
• Having a legend for node types and edge types to understand the relationships between the nodes (since graph is heterogenous) would be nice.
• Agree with Dimitris’s comment about the coarse structure, since the graph looks a bit dense and spread out. The coarse structure can be expanded into the main graph upon double-clicking (like it happens in TensorFlow computation graphs)
• I think it would be nice to have a quick navigation side-bar with the important anchor nodes. These could be two-level, dataset/model/application and then a search-able list of corresponding nodes.
• The action for panning around the graph and moving the nodes and edges around is same - click and drag. This can make navigation cumbersome sometimes if your cursor is accidentally over the node.
• Instead of the click opening the page corresponding to the entity - it would be nice to have a flashcard pop-up with the core information and a link for more details. It would be nice to have some basic info while checking out the graph.

Yifan:

• Works well on mobile; that's good!
• Not sure why it tries to do a force directed layout upon first load, before snapping to the final layout (which seems not force directed)
• Not sure if moving nodes should even be supported; I haven't seen this in other graph visualizations
• Some graph layout ideas: maybe try to group nodes of the same type, or maybe try to lay out most directed arrows from top to bottom
• Would be good to have zoom and and out buttons, since scroll wheel is not always available on all systems
• Consider not using red on the color scheme (has a strong "danger" connotation)
• Clicking should open a infobox instead of going to another page
