I think you can do it pretty fast this way:

var dataArr = ["Retail",1,"Utilities",1,"Food & Restaurant",3,"No Data",4,"Construction",0,"Non-profit",1,"Financial Services",12,"Technology",2,"Law",3,"Religion",3,"Retired",2,"Insurance",0,"Real Estate",2,"Audit",3,"Business Organizations",3,"Media & Marketing",0,"Education",3,"Transportation",0,"Manufacturing",0,"Entertainment & Sports",0,"Architecture & Engineering",0,"Cultural Institutions",0,"Government",0,"Banking",0,"Health Care",0,"Business Services",0];

var item = 0; // value of the item to remove

while (dataArr.indexOf(item) > -1) {
 dataArr.splice(dataArr.indexOf(item), 1);
}

console.log(dataArr);
