Last tick label does not appear in D3 Line Chart

I'm trying to write a generic multiline chart function based on Mike Bostock's example (https://bl.ocks.org/mbostock/3884955).
I'm facing an issue wherein, the last tick label on my Monthly graph x-axis does not show up. The last tick appears fine on the Weekly graph x-axis.
JS Fiddle Link:
http://jsfiddle.net/Q5Jag/11879/
I'm suspecting the issue here could be due to the range specified for the x-axis which for some reason ignores the last value. But I'm not exactly sure what is going on here. Could anyone help me debug ?
Here is my code:
function renderMultiLineChart(datafile, chartDiv, xAxisLabel, yAxisLabel, graphCadence){
var margin = {top: 20, right: 60, bottom: 80, left: 60},
width = 760 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
var parseDate = d3.timeParse("%m/%d/%y");
var x = d3.scaleUtc()
.range([0, width]);
var y = d3.scaleLinear()
.range([height, 0]);
var color = d3.scaleOrdinal(d3.schemeCategory10);
//var xAxis = d3.axisBottom(x).tickFormat(function(d){ return d.x;});
switch(graphCadence) {
case "Daily":
var xAxis = d3.axisBottom(x).ticks(d3.timeDay.every(1)).tickFormat(d3.timeFormat("%m/%d"))
break;
case "Weekly":
var xAxis = d3.axisBottom(x).ticks(d3.timeSaturday.every(1)).tickFormat(d3.timeFormat("%m/%d"))
break;
case "Monthly":
//var xAxis = d3.axisBottom(x).ticks(d3.timeDay.every(1))
var xAxis = d3.axisBottom(x).ticks(d3.timeMonth.every(1)).tickFormat(d3.utcFormat("%m/%d"))
break;
}
var yAxis = d3.axisLeft(y);
var line = d3.line()
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.count); })
var div = d3.select(chartDiv).append("div")

I believe the problem lies in a misalignment between how d3.timeMonth works and how your data is formatted. You see that d3.timeMonth is labeling the first of every month, whereas the data is grouped on the last day of every month. So when you call x.domain(d3.extent(data, function(d) { return d.date; }));, the last data point's date is less than the next label would have been.
One potential solution is to change your parse function to bump all your month dates forward by one day to make them line up with the first of the month. See below.
To remove any dates that end mid-month, you can filter the data set after parsing dates to clean it up.
function renderMultiLineChart(datafile, chartDiv, xAxisLabel, yAxisLabel, graphCadence){
var margin = {top: 20, right: 60, bottom: 80, left: 60},

How to properly calculate width for D3 Siluohette stacked Area chart

Hopefully Mike Bostock comes swinging in to my rescue on this one.
(EDIT: With the help of Andrea Crawford's answer below this is the working version)
JS Fiddle: https://jsfiddle.net/dfcarter/kd0dkrL8/
I have written a chart in d3 to allow on the fly user changes (colors, selected data, etc)
Well it is mainly working but when you remove the lower ordinals it stops centering on the graph and starts to creep downward.
Looks Fine - removing the first 3 seems fine
Looks Unacceptable - removing the Last 3 and the chart is toward the bottom of the graph area
The Core of the D3 for reference:
(The Fiddle works correctly I don't see why the external reference to spectrum is not working so look at the fiddle)
var $pop = $('#my_custom_menu'),
notHov = 1; // Hover flag
$pop.hover(function() {
notHov ^= 1;
}); // Toggle flag on hover
$(document).on('mouseup keyup', function(e) {
if (notHov || e.which == 27) $pop.fadeOut();
});
/////// CALL POPUP
$('.my_custom_menu').click(function() {
$pop.stop().fadeIn();
});

I'm not an expert on D3 so you may still want to wait for Mr. Bostock, but I think your issue is that inside your redraw function, you have this code:
y.domain([0, d3.max(data, function(d) {
if (!d.disabled) return d.y0 + d.y;
})]);
but if you look at the value of d, it doesn't actually have a disabled property.
You could add a disabled property to the values at the same time you add it to the parent:
legend.on('change', function(d) {
d.disabled = !d.disabled;
$.each(d.values, function(){
this.disabled = d.disabled;
});
d3.transition().duration(600).each(redraw);
});
There's probably a more elegant way to do that, but it seems to fix the issue.

d3 v4 version of stack function x and y

I am converting some v2 code to v4 and I am stuck at this point. where does the x an y functions go for v4? Also is this the right way to create nested values? Thanks
d3.stack()
.offset(d3.stackOffsetSilhouette)
.value(function(d) { return d.values; })
.x(function(d) { return d.date; })
.y(function(d) { return d.value; });
var nest = d3.nest()
.key(function(d) { return d.key; });
var layers = stack(nest.entries(mainVal));
Edited to add full code. Everything has been migrated to v4 but I'm just not sure about that section since layers is returning as an empty array.

That results in something similar to this:
http://bl.ocks.org/WillTurman/raw/4631136/
However, I would like to update this chart based on a query.
I found these to examples:
http://bl.ocks.org/d3noob/7030f35b72de721622b8
http://bl.ocks.org/mbostock/4060954
But I don't know how to apply then to my code. I would like to do something different then having a function just for update a chart. I would like to, inside the chart() function, be able to check if a chart already exists. If so, I would just update it (data, x, y), using a transition.

I would like to do something different then having a function just for update a chart. I would like to, inside the chart() function, be able to check if a chart already exists.
If you want to check if a chart already exists, you can first assign an id to that chart, and then check if something with that id already exists when you need to decide if you should update the chart or otherwise.
Something like this
var svg = d3.select(".chart").attr("align","center")
.append("svg")
.attr("id", "svg-elem")
Then, use something along these lines to decide what to call next.
if(!d3.select("#svg-elem").node()){
// chart doesn't yet exist.
// call chart initilization code?
} else {
// call chart update code
}

Hover d3.js Streamgraph

I am trying to fix a hover, tool tip problem on my stream graph. I have a data set of decades and immigration data. When I hover over the graph it only shows the data for one decade, but the entire graph shows all the data.
I also am trying to correct axis labels.
For instance, the data for Russia should be , at the highest point: 433,427
