Volume candle vis a vis normal candle

What is difference between these two types of candles?, which one is superior and why?

As per my understanding, a normal candle only tells you the Open, High, Low and Close in the selected time-frame. Volume candle takes it one step ahead by introducing the “width” element to a candle. Normal candles are all equally wide, but the width of a Volume candle tells you about the volume associated with the price movement. Hope this helps. Thanks.

I sincerely thank you for the revert but I don’t think it is real difference…I request all readers to
Please respond.
