2 completely different d3 charts on same page - d3.js

Question

I'm trying to get 2 completely different d3 charts (2 line charts but totally different data - one with several lines and negative data, other with one line positive data) on the same page.
Right now, I only get the first one to be generated and shown correctly on the HTML page, the second chart doesn't show at all (not even svg container is generated).
Here is my code:
(function() {
// Get the data
d3.json("../assets/js/json/temperature.json", function(data) {
// Set the dimensions of the canvas / graph
var margin = {top: 30, right: 20, bottom: 30, left: 25},
width = 600 - margin.left - margin.right,
height = 270 - margin.top - margin.bottom;
// Parse the date / time
var parseDate = d3.time.format("%Y-%m-%d %H:%M:%S").parse;
// Set the ranges
var x = d3.time.scale().range([0, width]);
var y = d3.scale.linear().range([height, 0]);
// Define the axes
var xAxis = d3.svg.axis().scale(x)
.orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
.orient("left").ticks(5);
// Define the line
var valueline = d3.svg.line()
.x(function(d) { return x(d.temps); })
.y(function(d) { return y(d.temperature); });
// prepare data
data.forEach(function(d) {
d.temps = parseDate(d.temps);
d.temperature = +d.temperature;
});
// Adds the svg canvas
var svg = d3.select("#graphTemp")
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
// Scale the range of the data on domain
x.domain(d3.extent(data, function(d) { return d.temps; }));
y.domain([0, d3.max(data, function(d) { return d.temperature; })]);
// Add the valueline path.
svg.append("path")
.attr("class", "line")
.attr("d", valueline(data));
// Add the X Axis
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
// Add the Y Axis
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.append("text")
.attr("transform", "rotate(-90)")
.attr("y", 6)
.attr("dy", ".71em")
.style("text-anchor", "end")
.text("Temperatures");
});
})();
(function(){
// loads the data and loads it into chart - main function
d3.json("../assets/js/json/maitrise.json", function(data) {
var m = {top: 20, right: 5, bottom: 30, left: 40},
w = 70 - m.left - m.right,
h = 30 - m.top - m.bottom;
var x = d3.scale.linear().domain([0, data.length]).range([0 + m.left, w - m.right]);
var y = d3.scale.linear()
.rangeRound([h, 0]);
var line = d3.svg.line()
.interpolate("cardinal")
.x(function(d,i) { return x(i); })
.y(function (d) { return y(d.value); });
var color = d3.scale.ordinal()
.range(["#28c6af","#ffd837","#e6443c","#9c8305","#d3c47c"]);
var svg2 = d3.select("#maitrisee").append("svg")
.attr("width", w + m.left + m.right)
.attr("height", h + m.top + m.bottom)
.append("g")
.attr("transform", "translate(" + m.left + "," + m.top + ")");
// prep axis variables
var xAxis2 = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis2 = d3.svg.axis()
.scale(y)
.orient("left");
//console.log("Inital Data", data);
var labelVar = 'id'; //A
var varNames = d3.keys(data[0])
.filter(function (key) { return key !== labelVar;}); //B
color.domain(varNames); //C
var seriesData = varNames.map(function (name) { //D
return {
name: name,
values: data.map(function (d) {
return {name: name, label: d[labelVar], value: +d[name]};
})
};
});
console.log("seriesData", seriesData);
y.domain([
d3.min(seriesData, function (c) {
return d3.min(c.values, function (d) { return d.value; });
}),
d3.max(seriesData, function (c) {
return d3.max(c.values, function (d) { return d.value; });
})
]);
var series = svg2.selectAll(".series")
.data(seriesData)
.enter().append("g")
.attr("class", function (d) { return d.name; });
series.append("path")
.attr("class", "line")
.attr("d", function (d) { return line(d.values); })
.style("stroke", function (d) { return color(d.name); })
.style("stroke-width", "2px")
.style("fill", "none");
});
})();

Answer 1

OK, I found where the error was coming from. There was a piece of javascript in the middle of the HTML page that stopped d3 to generate the second graph further down in the page.
Thanks for all the help!
