1. A method comprising:
analyzing time-stamp data collected associated with a plurality of elements of an industrial process to generate a set of times associated with each element in the plurality of elements, wherein the industrial process is a production line, wherein the plurality of elements of the industrial process comprises one or more of production stations in the production line and a set of transitions between the production stations, wherein the set of times associated with each element in the plurality of elements relates to a time duration associated with a product passing through the element, and wherein each element in the plurality of elements is associated with a corresponding characteristic time;
generating, based on the set of times associated with each element in the plurality of elements, a color coded visualization of the industrial process, wherein generating the color coded visualization comprises associating, based on the corresponding characteristic time, each of the plurality of elements of the industrial process with a corresponding color indicating a state of an element in the plurality of elements of the industrial process, wherein the state of each element relates to the set of times associated with the element, and wherein the corresponding color indicating the state of the element is selected from a color gradient and times associated with endpoints of the color gradient are based on the corresponding characteristic time; and
presenting, via a display, the color coded visualization of the industrial process.
