Generate Motion chart about jquery-csv HOT 1 CLOSED

By default, jquery-csv does not apply implicit casting. In short, the data 
inputted to the parser is a string so the result will be strings.

There are 2 reasons for this. First, CSV is a text-based format so it's faster 
to skip any implicit casting. Second, applying implicit casting by default 
makes the assumption that the output format should be scalar; when that is not 
desired it creates unexpected side-effects.

If you need the parser to apply implicit casting there is a parser hook called 
castToScalar() that will accomplish what you require.

The following snippet is copied directly from the Google Visualization API's 
example code.
   var parsedData = $.csv.toArrays(csv, {
        onParseValue: $.csv.hooks.castToScalar
    });

Note: In the 'options' argument, create an object literal with a property named 
onParseValue, and set the property's value to $.csv.hooks.castToScalar.
