## FAQs and How-tos

Below is a list of frequently asked questions, and common trip-ups.

#### General

1. When I click Preview, I don't see the latest changes on my map?

Did you click Save on the menu bar? Remember, Rhumbl does not automatically save for you. To see your latest changes in Preview mode, you must first save.

#### Data

1. I imported in my spreadsheet, but I don't see any nodes on the map?

Does Rhumbl think your entities are group-type entities instead of node-type entities? If so, add an extra column in your Adjacency List spreadsheet called is_node:: and enter true for every row that is a node.

2. What is the maximum number of entities or relationships that I can have in my data?

It depends on your data. Currently, it's more the number of relationships that is the limiting factor. We estimate around 3000 relationships is when you'll start hitting performance issues. We're working on this to increase the maximum data you can visualize.

3. Why do some of my entities say it's a good idea to specify a parent?

Whenever you have an entity that is not grouped under another entity, Rhumbl tells you that it's a good idea to specify a parent. This is because by grouping, Rhumbl can better arrange them on the map. For example, nodes under the same parent entity are clustered together.

The only entity that should not have a parent is the root entity — the top-most entity in your data.

#### Styling

1. How do I make edges thicker?

If you're using the Adjacency Matrix format, you can enter in a number that represents the “strength” of the edge. The higher the number, the thicker the edge.

Currently, there is no way to make edges thicker via the Adjacency List spreadsheet, but we're working on this feature!

2. How do I get links to show up as clickable links in the Info pane?

Rhumbl automatically recognizes any cell starting with the value http:// or https:// as a clickable link, and will display it as such.

The only step you need to do is to select the link property as an attribute to show up on the Info Pane, or by default, it doesn't.
