What is LM3915 VU Meter Circuit Diagram about?

This circuit diagram shows two integrated circuits (IC1 and IC2), which are LM3915N voltage-to-frequency converters, that are used to drive 19 light emitting diodes (LEDs) through three switches and various resistors and capacitors. IC1 controls LEDs 1 through 10 and IC2 controls LEDs 11 through 19 with the LED strings arranged in columns that can each be activated independently using the three switches.
