Sorting through nested objects on the client sideorFiltering

I have a d3.js scatterplot based off of this: http://bl.ocks.org/nsonnad/4481531

I'm attempting to implement a feature that enables filtering based on different criteria, such as country in the provided example (each represented by a color bubble).

The data is sourced from a .csv file and when logged, it appears as an object structure like this:

[0 … 99]
   0: Object
       attribute: "INFJ"
       category: "Personality Type"
       incidence: "1.04"
       index_value: "65"
       main_grouping: "Behaviors"
     __proto__: Object
   1: Object
   2: Object
   3: Object
    ETC...

My goal is to filter all rows with a specific main_grouping. While I can retrieve a list of all main_groupings, I need help moving forward.

d3.csv("example.csv", function(data) {
    $.each(data, function (index, value) {
        console.log(value.main_grouping);
        });

I am unsure how to proceed next or how to achieve the desired outcome - selecting a certain main_grouping (to be done via a dropdown menu) and retrieving only those rows for use in the scatterplot rendering script.

Since there's no option for server-side processing, the solution has to be implemented client-side.

Answer №1

Utilize the array method filter to achieve this task

d3.csv("example.csv", function(data) {
data_filtered = data.filter(function(d){
    return d.main_grouping == selected_grouping;
  });
}
