Loading csv file fails to load in js file for public assets using play framework with scala

Question

In Play framework for scala I'm using data.csv in the js file line_graph.js and line_graph.js is loaded but data.csv is not getting loaded. How shall i load data in js file.

<script src="@routes.Assets.at("js/line_graph.js")" type="text/javascript"></script>

 <a  href="@routes.Assets.at("js/data.csv")"></a>
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/4.2.2/d3.js"></script>

My assets structure.

public /js /line_graph.js ,data.csv

my routes

GET     /assets/*file               controllers.Assets.at(path="/public", file)

application.conf

play.filters.headers.contentSecurityPolicy = "default-src *; script-src 'self' cdnjs.cloudflare.com code.jquery.com"

line_graph.js code

d3.csv("data.csv", function(error, data) {
    if (error)
        throw error;
    data.forEach(function(d) {
        d.number = d.number;
        d.iteration1 = +d.iteration1, d.iteration2 = +d.iteration2;
    });

Answer 1

In your file line_graph.js you don't use the correct url for the csv file. Try with:

d3.csv("/assets/js/data.csv", function(error, data) {
  ...
