Course Project: Shiny Application and Reproducible Pitch

This presentation was built as part of a deliverable for the course Developing Data Products as part of the Coursera Data Science Specialization. Course 9 - Week 4. (c9w4b)

The data used was based in Diamonds information.

• Running code: https://dcialdella.shinyapps.io/c9w4/
• The source code: https://github.com/dcialdella/c9w4
• The PPT stored on: https://dcialdella.shinyapps.io/c9w4/
• Relevant info: http://www.lumeradiamonds.com/diamond-education/index

Rules to take care about it:

• Shiny used to build data product application demo.
• R-presentation editor to create the Presentation associated.
• Information provided by Cityhall Alcalá de Henares.

Welcome page, show VARs to complete/Select, brief detail about the data and the information provided. VARIABLES

• Price - will show line with this referenced value
• Carat - Used to select Carat (between 0.2 and 5.01)
• Color - Select quality (0-all, 1 to 7 means I to D quality)
• Records - Select records used for the process (try to test it with a few records first)
• Show/Hide - Used as boolean var to show/hide reference lines on graphics
