Discuss why healthcare managers prefer graphical representation of data instead of numerical data used in their decision-making process.  Which graphical method or type of chart would you use to demonstrate side-by-side comparison: Readmissions for the last 10-year period and a superimposed trend line showing increase/decrease readmissions? What are merits and demerits of this type of data representation? Develop a visual representation example to illustrate your answer. Create a basic data set table for no more than 10 lines to use as the visualization base. Make sure to clearly label the columns and lines. 

Which type of visual representation would you use to present proportions of three readmission causes to the management: early discharge, infections, and non-compliance. What are the advantages and limitations of this method for data visualization?
