Answer 1

Explanation:

Barchart or Gantt Chart:

Bar charts were introduced by Henery Gantt around 1900 A.D., therefore they are also called Gantt charts.
A bar chart is a graphical representation of activity v/s time. It provides a visual representation of a project's timeline, showing the start and end dates of various tasks or activities, as well as their dependencies and the overall project schedule.
Usually horizontal axis represents the time duration and the vertical axis represents activities or jobs to be performed.
Activities are shown with the help of a bar.
The beginning and end of each bar show the "time of start" and "time of finish" of the activity respectively.
Therefore the length of the bar represents the time required for the completion of that activity.
Gantt charts can show task dependencies, indicating which tasks must be completed before others can begin.
Illustration is given on how the activities are to be distributed over the project timeline.
