- Data visualizations should have a clear purpose and audience.
- Choose the right type of viz or chart for your data.

What is the value of visualization?
Visualization of data makes it possible for re- searchers, analysts, engineers, and the lay audience to obtain insight in these data in an efficient and effective way, thanks to the unique capabilities of the human visual system, which enables us to detect interesting features and patterns in short time.
What is the best technique to visualize changes in prices over time?
Bar charts work best for time series when you’re dealing with distinct points in time (as opposed to more continuous data). They tend to work better when you have data points that are evenly spaced in time.
How effective is the visualization Why?
Data visualization gives us a clear idea of what the information means by giving it visual context through maps or graphs. This makes the data more natural for the human mind to comprehend and therefore makes it easier to identify trends, patterns, and outliers within large data sets.

What is the use of the Rep function?
In this section, I will introduce the rep function and provide a basic use case in the context of creating a data frame from the simulated data we have generated. The rep function replicates the values in a given object (a vector or a function) a specified number of times. The rep function uses the following syntax and arguments:
Can you be 95% sure of the true value?
We happen to be pretty sure that any true population difference will be less than 0.01 (see here), hence if p2 – p1 is between -0.09 and +0.09, we can be pretty sure that our 95% interval doescontain the true value.
What do the arguments mean in a replication function?
Where “x” is the value to be replicated or the vector containing values to be replicated, and “…” denotes additional arguments, such as “times=” (which specifies the number of times to replicate “x”), “each=” (which specifies the number of times to repeat each element of “x”), and “len=” (which specifies the desired length of an output vector).
