Is there a way to eliminate double quotes from nested array information?
["[a,b,c],[b,c,d],[e,f,g]"]
Transforming it into this array:
[[a,b,c],[b,c,d],[e,f,g]]

Valid values for variables such as a, b, c, are essential for making sense of the code and ensuring its execution.
An approach to achieve this is by creating a valid JSON string and then parsing it:
var arr = ["[1,2,3],[4,5,6],[7,8,9]"];
var json = "{ \"x\" : [" + arr[0] + "] }";
console.log(json);
var res = JSON.parse(json);
console.log(res.x);
console.log(res.x[0]);
console.log(res.x[1]);
console.log(res.x[2]);Another method involves using eval():
var arr = ["[1,2,3],[4,5,6],[7,8,9]"];
var res = eval("[" + arr[0] + "]");
console.log(res);
console.log(res[0]);
console.log(res[1]);
console.log(res[2]);Important Note - Be cautious when using eval() as it can execute any JavaScript code provided, unlike JSON.parse() which is limited to static object data only.
Update - If utilizing the literal variables like a,b,c, they must be predefined in the program's scope. In this case, you can only utilize eval() since it executes within the program's scope whereas JSON.parse() does not.
For instance:
var a = 1,
b = "hello",
c = new Date(),
d = ["p", "q", "r"],
e = 5,
f = new Object(),
g = 7;
var arr = ["[a,b,c],[b,c,d],[e,f,g]"];
var res = eval("[" + arr[0] + "]");
console.log(res);
console.log(res[0]);
console.log(res[1]);
console.log(res[2]);I'm struggling with understanding the correct structure for writing D3 code. For example: In the code snippet below, I noticed that if I place the 3rd section (Chart Title) of the code after creating the svg element, the title text doesn't displ ...
