I think this test is broken?

my finished code passes task 1, then when giving the same code for task 2 it says task 1 is now failed.

js/app.js
// height and width of the svg
var height = 800, width = 500;

var padding = 50;

var viz = d3.select("#viz-wrapper")
    .append('svg')
    .attr('id', 'viz')
    .attr('height', height)
    .attr('width', width);

d3.csv('app/climate_data_truncated.csv', function(data) {

    dots = viz.selectAll('circle')
        .data(data)
        .enter()
        .append('circle');
    dots.attr('r', function(d) {return Math.abs(d.TMIN) / 10});
    dots.attr('r', function(d) {return Math.abs(d.TMIN) / 10})
        .attr('cx', function(d) {return Math.max(0 + padding, Math.random() * width - padding)})
        .attr('cy', function(d) {return Math.max(0 + padding, Math.random() * height - padding )})
        .style('stroke', function(d) {
            year = d.DATE.substring(0,4)
            if (year === "1974") {
                return "blue"
            }
            else {
                return "#fdfdfd"
            })
        .style('fill', function(d) {
            year = d.DATE.substring(0,4)
            if (year === "1973") {
                return "blue"
            }
            else {
                return "#fdfdfd"
            }
        });
});
