Visualising data flows using Custom Visuals

Assume a 4 column dataset (a small sample) as follows:

City of Origin City of destination Mode of Transport Passengers travelled
New Delhi Pune Air 123
New Delhi Mumbai Air 213
New Delhi Kolkata Air 125
Chandigarh Jammu Bus 785
Chandigarh Amritsar Train 567

Given this dataset, one may want answers to the following questions:

1. Of all those passengers who originated their journey (City of Origin) from Chandigarh, how many terminated their journey (City of destination) in New Delhi via different modes of transport; and
2. Of all those passengers who terminated their journey (City of destination) in Jammu, how many arrived in Amritsar (City of Origin) via different modes of transport; and
3. Of all those passengers who travelled by Bus, how many travelled from City A (City of Origin) to City X,Y,Z (City of destination)

While one can analyse/slice and dice this data using Pivot Tables, one cannot visualize this data very clearly (even after creating a Pivot chart).  I have attempted to visualize this data using a software called PowerBI desktop (a free for download and use Business Intelligence software from Microsoft which rolls all of Excel's BI tools into 1 - PowerPivot, Power Query, Power Map and Power View).

You may download the source Excel workbook and the Power BI desktop workbook from this link.

Sales data modelling and interactive visualisations

{30 Comments}

Visualise Sales Data of a Non-Alcoholic Beverage Company with basic columnar information such as Date of Sale, Time of Sale, Brand, Stock Keeping Unit (SKU), State, City, Quantity sold, Unit Price and Salesman Code.  In this sales dataset, each line item represents one visit for one SKU.  If nothing is sold in a certain visit, then the SKU column displays No Sale.  So effectively there is a line item for each visit whether or not something is sold in that visit.

From this simple Sales dataset, here are a few questions which one may need to find answers to:

1. How did the Company perform (in both years 2013 and 2014) on two of the most critical Key Performance Indicators (KPI's) - Quantity sold and Number of Visits.  Also, what is the month wise break up of these two KPI's.

2. Study and slice the two KPI's from various perspectives such as "Type of Outlet visited", "Type of Visit" - Scheduled or Unscheduled, "Day of week", "Brand", "Sub brand".

3. Over a period of time, how did various SKU's fair on the twin planks of "Effort" i.e. Number of visits YTD and "Business Generated" i.e. Quantity sold YTD.

4. Analyse the performance of the Company on both KPI's:
a. During Festive season/Promotional periods/Events; and
b. During different months of the same year; and
c. During same month of different years; and
d. Quarter to Date

5. "Complimentary Product sold Analysis" - Analysis displayed on online retailers such as Amazon.com - "Customers who bought this also bought this".  So in the Sales dataset referred to above, one may want to know "In this month, outlets which bought this SKU, also bought this much quantity of these other SKU's."

6. "Outlet Rank slippage" - Which are the Top 10 Outlets in 2013 and what rank did they maintain in 2014.  What is the proportion of quantity sold by each of the Top 10 outlets of 2013 to:
a. Total quantity sold by all Top 10 outlets in 2013; and
b. Total quantity sold by all outlets in 2013

7. In any selected month, which new outlets did the Company forge partnerships with

8. Which employees visited their assigned outlets once in two or three weeks instead of visiting them once every week (as required by Management).

9. Which outlets were not visited at all in a particular month

10. Business generated from loyal Customers - Loyal Customers are those who transacted with the Company in a chosen month and in the previous 2 months.

These are only a few of my favourite questions which I needed answers to when I first reviewed this Sales Data.  Using Microsoft Excel's Business Intelligence Tools (Power Query, PowerPivot and Power View), I could answer all questions stated above and a lot more.
