y returns as NaN even after fixing capitalization for radio and sales about machine-learning-with-js HOT 2 OPEN

On my end, using the "json" event was what caused the lack of data. I solved the issue by using the "data" event and manually converting to JSON instead:

csv().fromFile( csvFilePath ).on( "data", ( data ) => {
	var jsonObj = JSON.parse( data.toString() );
	csvData.push( jsonObj );
	console.log( "Data", jsonObj );
} ).on( "done", () => {
	dressData();		// Acquires data points
	performRegression();
} );

Hope this helps.

change row.radio to row.Radio
change row.sales to row.Sales.

It's b'coz label name is different.
