Why do these 9 U.S. cities not correspond to their actual locations on a D3 map when I plot them using long/lat with an Albers USA projection?

I'm trying to set up what seemed to be a basic D3 map of the U.S., with 9 of the most populated cities marked in circles, but have come up against what must be a very obvious, but confounding problem.

I'm using an Albers USA projection, a U.S. states GeoJSON file, and a .csv that includes:

1. The city name
2. The 2014 estimated population
3. The latitude
4. The longitude

I've calculated the long/lat values using Google Fusion tables' geocoding feature, and they match up with those available on Scott Murray's D3 book github page.

When I try to plot a circle where each city should be, almost every single one is out of place. Of the 9 cities I'm trying to plot — NYC, Philadelphia, Chicago, Houston, Dallas, San Antonio, Phoenix, San Diego, LA — only NYC and Philadelphia show up relatively intact. Chicago's shifted over towards Minneapolis. San Diego and LA are a mess. Cities in Texas and Arizona have disappeared from their states altogether.

Here's the d3.csv code:

        d3.csv("city_pop.csv", function(data){
                console.log(data);
            var rScale = d3.scale.linear()
                            .domain([0, d3.max(data, function(d){
                                return parseFloat(d.estimate_2014);
                            })])
                            .range([1,15]);

            dataset = data;

            svg.selectAll("circle")
            .data(dataset)
            .enter()
            .append("circle")
            .attr({
                "cx": function(d) { return projection([d.lon, d.lat])[0];},
                "cy": function(d) { return projection([d.lon, d.lat])[1];},
                "r": function (d) { return rScale(parseFloat(d.estimate_2014));}
            })
            .style({
                "fill": "red",
                "opacity": 0.8
            });
        });

I've been playing with this all day. Does anyone have any ideas? I've been banging my head against the wall for what feels like forever, and am wholly lost.

tl;dr: why do the cities in this D3 map http://bl.ocks.org/iblind/2e90a6f516fee793380e not show up where they should be showing up?

The base data is wrong (city_pop.csv). Run your latitudes and longitudes through Google Map and you'll see the same pattern forms. For example Philadelphia,Pennsylvania (37.15477,-94.486114) is not where Pennsylvania is - https://www.google.ee/maps/place/37%C2%B009'17.2%22N+94%C2%B029'10.0%22W/@37.15477,-94.486114,4z/data=!4m2!3m1!1s0x0:0x0?hl=en
