1. A visualization system comprising:
a first storage section configured to store manufacturing log information about manufacturing of products grouped in manufacturing units, products of each unit being manufactured through a plurality of manufacturing processes in order, the manufacturing log information including a start time and an end time of each of the manufacturing processes;
a second storage section configured to store chronological history information of process characteristic factors corresponding to factors affecting quality characteristics in the manufacturing processes;
a first creation section configured to create a time axis for the process characteristic factors in synchronization with a time course of the manufacturing log information, create a display object representing a state or a change of each of the process characteristic factors based on the chronological history information, and place the display object on the time axis to create a timeline object of each of the process characteristic factors;
a second creation section configured to create, for each of the product manufacturing units, a line segment connecting a start time or an end time of a first process on a time axis of the first process to a start time or an end time of a second process subsequent to the first process on a time axis of the second process in parallel with the time axis of the first process; and
a display control section configured to display, on a display apparatus, a process characteristic factor timeline screen including timeline objects of the respective process characteristic factors arranged in parallel,
wherein the first creation section is configured to create the timeline objects of the process characteristics factors in synchronization with a time course of a selected one of the manufacturing processes.
