## What is Graph Editor?

A graph (a mathematical concept) is used to describe the intricate relationships between various things in reality. Nodes represent an object, and edges represent connections between objects.

Graph Editor provides a visual way to create and edit Graph based on the open source software Graphviz. Graphviz is a visual graphics tool open sourced by AT&T Research and Lucent Bell Labs, which can be easily used to draw structured graph networks and supports output in multiple formats.

Graph Editor supports creating directed and undirected graphs, using dot layout. Usually Graphviz uses scripts as input, and Graph Editor can create complex and beautiful graph structures just by clicking on the screen, which is completely automaticly. You can set the color, width, and line style of nodes and edges, and you can also group some nodes into a subgraph. Graph Editor performs various operations on Graph directly in memory, and users do not have to worry about the calculation time of complex graphs.

Graph Editor supports exporting the created Graph to PNG, JPG, PDF, and SVG files, and will support more export types in the future.

#More graph concepts
In mathematics, a graph is a structure described by a set of objects, some pairs of which are "related" in some sense. These objects correspond to mathematical abstractions called vertices (also called nodes or points), and each related pair of vertices is called an edge (also called a link or line). Typically, graphs are graphically depicted as a set of points or rings of vertices, connected by lines or curves of edges. Graph is one of the research objects of discrete mathematics.

### 1/5 — Abysmal profit gain method

*2025-05-16*

I cannot BEGIN to comprehend why mobile app developers have the worst sense of "What features should be paywalled and what features should I leave untouched?" known to mankind. WHY is making graphs limited to only 3??? I can literally just copy a graph file and modify it from there, completely circumventing your in-app graph creation sequence! What is even the point of this limitation? "Pay me to continue using my app"? That's not a subscription for extra features that aren't required to use the app, that's literally paywalling the app! ..Or at least what you intended to do.
I've been searching for an app that allows me to make node-based graphs (Which is really difficult because every search engine thinks you're talking about anything BUT those, and if you search for too specific of terms, then it'll give basically nothing...), and this app is the FINAL straw for me. I've had it. I'm making an app that allows the user to make node-based graphs, I'm allowing the user to use the app and have lots of useful features for FREE, and I'm making it BETTER than whatever this is. I don't care if it'll only really be usable on computers because it'll be made with the Godot engine + I have no idea how to create apps for Apple devices/phones in general, I'll have accomplished something of more value than whatever this software is.

### 4/5 — 无法充值！

*2024-12-14*

会一直卡在选择套餐，无法加载！

### 4/5 — Good for what I was looking for

*2024-10-03*

What I was looking for but have a couple suggestions:
- Should be able to move nodes and lines freely over to wherever you want them
- Change it so notes only show up on the screen if you click on them

### 1/5 — 为什么闪退😖

*2024-05-31*

前面好好的，做着做着就开始闪退了

### 5/5 — Very cool!

*2022-12-30*

I’m going to see if I can view the DOT!

### 4/5 — Hassle-free diagramming

*2022-10-10*

This app is the easiest way to create clean diagrams on a phone.

Would be great to support more layouts that Graphviz offers.

### 5/5 — 非常好的软件

*2022-07-28*

作图神器，一定给身边的朋友推荐

### 5/5 — 太棒了，终于找到一款好用的作图工具

*2022-07-28*

作为一名程序员，有了这个工具，轻松点几下，就可以制作出程序的结构图、流程图。给开发者一个建议，能不能增加一下动画效果，那样看起来就更酷炫了。

### 5/5 — 傻瓜式作图App，体验很棒

*2022-07-28*

也不需要太动脑筋，屏幕上点点划划描述出来所想的东西，就能做出满意的流程图、结构图来，还能当脑图使用，很棒了。

### 5/5 — 非常棒的app

*2022-07-27*

App 有点酷，点几下就生成一个流程图：正好需要一个简捷作图的App，在屏幕上点几下就能达到我想要的效果。默认样式已经OK，还支持对每个图元素自定义属性，很不错。
