[Solved]-Simple line graph with dates in D3-d3.js

I've updated your jsfiddle to do what you want here. Briefly I did the following:

• Use a time scale instead of a linear scale. Then you can specify d3.time.days, 1 as ticks.
• A path is filled by default with no stroke. See the CSS I've added.
• Use the .tickFormat function with an appropriate format.
• Should be fixed by using a time scale and appropriate tick spec.
