I'm trying to get a line graph by getting the datas from the external json file,
<!DOCTYPE html>
<meta charset="utf-8">
<head>
<style>
body {
font: 10px sans-serif;
}
.axis path,
.axis line {
fill: none;
stroke: #000;
shape-rendering: crispEdges;
}
.x.axis path {
display: none;
}
.line {
fill: none;
stroke: steelblue;
stroke-width: 1.5px;
}
</style>
</head>
<body>
<script src="http://d3js.org/d3.v3.js"></script>
<script>
var margin = {top: 20, right: 20, bottom: 30, left: 50},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var parseDate = d3.time.format("%d-%b-%y").parse;
var x = d3.time.scale()
.range([0, width]);
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var line = d3.svg.line()
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.close); });
var svg = d3.select("body").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 + ")");
d3.json("data.json", function(error, data) {
data.forEach(function(d) {
d.date = parseDate(d.date);
d.close = +d.close;
});
x.domain(d3.extent(data, function(d) { return d.date; }));
y.domain(d3.extent(data, function(d) { return d.close; }));
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
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("Price ($)");
svg.append("path")
.datum(data)
.attr("class", "line")
.attr("d", line);
});
</script>
</body>
</html>
In data.json
[
{"date":"1-May-12","close":582.13},
{"date":"30-Apr-12","close":583.98},
{"date":"27-Apr-12","close":603.00},
{"date":"26-Apr-12","close":607.70},
{"date":"25-Apr-12","close":610.00},
{"date":"24-Apr-12","close":560.28}
]
It works fine in firefox and safari. But not in chrome. I'm getting these errors:
XMLHttpRequest cannot load ../Graphs/data.json. Cross origin requests are only supported for HTTP. d3.v3.js:1878 xhr.send d3.v3.js:1878 xhr.(anonymous function) d3.v3.js:1864 d3_xhr d3.v3.js:1886 d3.json d3.v3.js:8954 (anonymous function) graph.html:63

Can anyone tel me what the problem is? Thanks.
