Loading Data

To load multiple (arbitrary number) CSV files:

var filesArray = ["myrandedata.csv","myrandndata.csv","myrandudata.csv"];                

var remaining = filesArray.length;

filesArray.forEach( function(f) {                                                        
    d3.csv(f, function(data) {                                                           
        mydata[f] = data;
        if (!--remaining) doSomething();                                                 
    });                                                                                  
});

    filesArray.forEach( function(f) {                                                    
        console.log( mydata[f] );
