d3.js - D3: Is it possible to add multiple (more than 2) edges between nodes? -


this question has answer here:

i constructing d3 force graph visualize network traffic. need link 2 nodes more 2 paths. possible? appreciated.

nothing prevents drawing multiple edges between nodes. thing force directed graph layout made 2 nodes share 1 link. recommend following:

  • from force directed graph point of view have 1 link.
  • on drawing point of view, draw multiple edges if both nodes have multiple edges.

which give following data structure edges: 

links = {     source: 0, //index of source node     target: 0 //index of target node     representations : [{color: "red"}, {color:"blue"}] }

thus when give links force directed graph, won't complain. when draw link can iterate through representations array draw different links.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
