Timeline Distribution graph

#### Description

The exponential experiment consists of running a Poisson process until the time of the first arrival. The arrival is shown as a red dot in the timeline. The probability density function and moments of the arrival $$T$$ are shown in blue in the distribution graph, and are recorded in the distribution table. On each update, the empirical density function and moments are shown in red in the distribution graph and are recorded in the distribution table. The arrival time is recorded on each update. The parameter is the rate of the process $$r$$ which can be varied with the input control.
