I am currently creating a dynamic diagram using d3.js that incorporates hierarchical data. The goal is to make it interactive so that users can manipulate the hierarchy by adding or removing data values and children. I'm wondering if there is a way to dynamically utilize JSON within the browser to achieve this. If not, are there any alternative methods you would recommend?
Thank you in advance!
Transform your JSON data into an object by utilizing JSON.parse (consider using the JSON2 library for compatibility), adjust it as required, and then when you require the JSON data again (e.g. sending it back to the server), convert it back to a string using JSON.stringify
If you're unsure about how JSON works, think of it as a regular JS object that you can define like this:
var myJson = {
name: "example",
type: "sample",
items: [{}, {}]
}
When you have a string representing JSON data, you can easily parse it using:
var jsonData = '{"name":"example","type":"sample",items: [{}, {}]}',
objData = JSON.parse(jsonData);
You can manipulate the data with normal JavaScript functions. For more information on JSON and JavaScript, check out http://www.json.org/js.html
