I try to import a local .json-file using d3.json()
.
The file filename.json
is stored in the same folder as my html file.
Yet the (json)-parameter is null.
d3.json("filename.json", function(json) {
root = json;
root.x0 = h / 2;
root.y0 = 0;});
. . .
}
My code is basically the same as in this d3.js example
If you're running in a browser, you cannot load local files.
But it's fairly easy to run a dev server, on the commandline, simply cd
into the directory with your files, then:
python -m SimpleHTTPServer
(or python -m http.server
using python 3)
Now in your browser, go to localhost:3000
(or :8000
or whatever is shown on the commandline).
The following used to work in older versions of d3:
var json = {"my": "json"};
d3.json(json, function(json) {
root = json;
root.x0 = h / 2;
root.y0 = 0;
});
