I was looking through my .xcdatamodel and I noticed that there was an arrow that doesn't seem to represent anything(I can't post images so here's an example behind a link):

What does this represent? Thanks in advance.
Those arrows mean that one entity is a child of another. It goes from the child entity to the parent entity.

When I render my model these black lines/patterns appear all over it.
I tried recalculating normals, deleted doubles, and checked for extra faces, but everything seems alright.
Other models that I created from the same base model are ok, so I really don't know where the problem comes from. In the picture they also have th same material so it's not that either.
The two rendered models side by side:
Anyone have an idea of how I can fix this?

For some reason, you have double mirror modifier in second mesh, remove one of them
Is there a way in Cytoscape.js to connect two parent nodes to a child node like the example in the picture?
Sorry if the question is something very basic but I couldn't find it in the documentation (maybe I have missed it).
All I could do was to create an edge between one parent and the child and another edge between the other parent and the child, which looks kind of messy and won't help me in the visualization of a family tree.
Use segments edges to draw edges made of multiple straight lines: http://js.cytoscape.org/#style/segments-edges
I would like to have edges that are straight with right angles, similar to the family tree layout mentioned here: Styling edges in Cytoscape.js for a Family Tree
I've also attached an image showing what I would like to achieve.
In the link above they mention hyperedges, and changing the curve-style to "segments". I've done that, but there are only 2 segments and they do not form a right angle. There are some attributes that can be set for the segments, but I have not figured out how to make them work. Any help would be appreciated.
You have to calculate the points where the lines should be bent and set the segment style properties appropriately.
If you want an alternative way of specifying bent edges, you could investigate zigzag edges: https://github.com/cytoscape/cytoscape.js/issues/882
I'm using Cytoscape JS to create a network. This is a large network and I need to hide some nodes to be more readable, but I can't redraw my network not including the hiding nodes.
How can I redraw using auto-layout after hiding some nodes?
It's not clear to me exactly what you mean. An example would probably help. There are different semantics for hidden versus removed elements, and it sounds like perhaps you want the elements removed.
I ended up solving similar problem by just having two instances of Cytoscape.js on a page. First is headless one (invisible, with no HTML-representation) that stores all data I have. Second one is visible and has a subset of objects I want to be visible and layouted at the moment.
Copying elements between instances is extremely easy, like:
cy.add(datacy.$('#elem1'));
I have a kind a graph, I found it while googling "tree graph" though it doesn't look like a normal tree-graph. So I was wondering, is it also just called a "tree-graph" or has it a more specific name? I want to look up more info about them, though can't really search for it without a proper name.
Thanks a lot!
PS. I'm not sure if this is the correct place to ask this, if it's not, please direct me to the proper place. Thanks.
Google calls it a Treemap and provides several examples and an ontology. They define the treemap as follows:
A visual representation of a data tree, where each node can have zero or more children, and one parent (except for the root, which has no parents). Each node is displayed as a rectangle, sized and colored according to values that you assign. Sizes and colors are valued relative to all other nodes in the graph.

It's typically called a "heat map" or "heat chart".
That's a Treemap:
Treemaps display hierarchical (tree-structured) data as a set of
nested rectangles. Each branch of the tree is given a rectangle, which
is then tiled with smaller rectangles representing sub-branches. A
leaf node's rectangle has an area proportional to a specified
dimension on the data. Often the leaf nodes are colored to show a
separate dimension of the data.
