cytoscape.js

Based on this question and answer , I've made this JSFiddle . What I'm trying to do is to find a way to properly export / import JSON data to cytoscape.js. I'm using JSON.stringify(cy.json()) to get JSON data from elements, and on the other hand I'm cleaning the cy area and using cy.add(text-input) to add the elements back. I.e.: you can add a node, copy it's JSON data generated, then you can refresh the browser and paste the JSON data from node directly, tryng to add it to cy . But I couldn't get this to work, and I can't really figure out where I'm wrong (probably using the cy.add function).

I saw in the cytoscape.js tutorial that there are ways to represent the graph as image (png, jpg), but there is a way to represent it as regular graph, and if the user would want he can save it as image by click on button or similar option? Didn't find simple way for that. I am using python flask as my server side and cytoscape js for the graphes. maxkfranz You don't need server side code to save files from the browser anymore. You can save files using the saveAs() API in JS. Here's a polyfill: https://github.com/eligrey/FileSaver.js/ If you want the graph data, it would just be var jsonBlob =

What is the difference between D3.js and Cytoscape.js? Why would someone choose Cytoscape over D3.js? D3 is for charts and mostly static graphs. Cytoscape.js lets you manipulate highly-customisable and interactive graphs, and has an API as easy to use as jQuery. D3 is for arbitrary SVG . This means that although it can be used to make lots of different things, you have to build the renderer, interaction, and model yourself. Sometimes that's what you need. (Note SVG tends not to be able to performantly render highly complex scenes with lots of SVG elements, so evaluate your app's requirements

I am working on a web project for network visualization. I am writing my code in R using Shiny. And I want to display my graph using Cytoscape.js I've searched the web for some kind of source code doing this. But I couldn't find anything. The webpage of Cytoscape.js is not enough for me cause I am not expert in js and can't use the examples. Briefly, I have Adjacency matrix of my graph and want to use it with cytoscpae.js. Do you know any source code or a tutorial of the steps I should go through? Cytoscape.js supports JSON for input, so as long as your R/Shiny code can produce that, you

Is there a way to add nodes and edges to Cytoscape graph with concentric layout? Cy.add() function adds the nodes and edges to the graph without the init styling. Only way I can this, is by building the graph everytime I add a new node or edge When you add a node, it is positioned where you specify -- in the position field in its JSON . If you don't want to manually specify a position, then run a layout . In your specific case, you should probably be running the concentric layout again with the same options. 来源： https://stackoverflow.com/questions/38964733/how-to-dynamically-add-nodes-to

I have a 11MB JSON graph file with about 45K edges and 73K nodes without x, y locations, and I want to display this graph using the BFS layout. I am using promise/deferred to load the file. I haven't been able get Cytoscape to display this graph on chrome. So: Are there some special techniques for displaying large graphs? What is the largest graph anyone has displayed using cytoscape.js? If cytoscape.js won't work are there other JS frameworks that will work for large graphs? You are limited by the performance of the browsers themselves. Cytoscape.js uses several techniques to optimise
