[Enhancement] data schema for the graph should be an object instead of array

[xubinzheng]

Detailed description

Enhancement: use object instead of an array for data in graphs

Seems the data schema in Carbon has to be nested array. However, by using GraphQL or some other framework, the array could only have one single type.

as shown in the screenshot, the data schema is like
[ [[value1, value2, value3], title1] , [[valueA, valueB, valueC], title2] ]

Is this issue related to a specific component?
Seems all components

What did you expect to happen? What happened instead? What would you like to see changed?

maybe support something like

[
{
data: [value1, value2, value3],
title: title1
} ,
{
data: [valueA, valueB, valueC],
title: title2
}
]

as data schema
