A baloon emerging on the importance of Big DataBig Data is not large data, Big Data is complex data.Strategical datasets may not big but quite complex
What is big data?

We downloaded FINTURK dataset from the site of BRSA and anotated it by NUTS factors.
Our software read this data from an excel file with the name of “dataset”
From now on “dataset” means our NUTS Credit Loans FINTURK data

What is ggplot2 and Grammar of Graphics ?
Grammer of graphics represents and abstraction of graphics ideas/objects
Think ‘verb’, ‘noun’, ‘adjective’ for graphics Allows for a ‘theory’ of graphics on which to build

ggplot2 Graphics Package
• How to create basic plots (xyplot, scatterplots, histograms, baloon, facet, density and violin) using ggplot() function of ggplot2 package
• Setting vs. mapping• How to add extra variables with aesthetics (like
color, shape, and size) or faceting

Grammer of Graphics ?
‘In brief, the grammer tells us that a statistical graphic is a mapping from data to aesthetic attributes (color, shape, size) of geometric object (point, lines, bars).The plot may also contain stastistical transformations of data and drawn on a specific coordinate system’

Styles of Graphs
• We apply four types off ggplot2 graphical styles with ggplot2 geoms
1. Scatterplot with geom_point()2. Densityplot with geom_density()3. Violinplot with geom_violin()4. Smooth with geom_smooth()and facetplot with facet_grid()

Description of Baloon
Graphs
Baloon graphs of ggplot2 package can show us
3-dimensional relations distributed according 1-3
factors in scatterplot form.
With this type 2-dimensional numerical relations
can be represented under effect of 3rd numerical
value.

• Density Graphs are the continuous version of Histograms
• They plot a single numerical variable against their frequency.
• We can detect single or multiple peaks of density graphs and pinpoint the effective factors.
• On the other hand soperposing density graphs acording the factors with different colors provide us with information of the effect of the factors
• Logarithmic scale leads a more stable density formations for financial data.

Description of Violin Graphs
• Violin Graphs can be seen as two-dimensional density graphs
• Violin Graphs are very important for Risk Analysis of financial Data
• Through the mean of X-axis Y-density graph occurs with mirror copy
• Usually Violin Graphs comes with Mushroom, Pottery and Bottle formations
• Mushroom formation represents a risk concentration on hig order values of financial data
• Pottery means risk on the medium order
• and the bottle menas risk on the lower orders

Description of
PowerLaw Graphs
Power law distributions are usually used to model data whose frequency of an event varies as a power of some attribute of that event.
A numeric constant giving the power-law exponent and describes a scale free rate of change
Our POWERLAW ANALYSIS DataMining technique basicly a straigt line smoothing of double logatithmic data
This technique especially powerful on describing Risk Profiles of financial data
Our procedure for analyzing the data will follow the procedure in the paper: POWERLAW

• Facet graphs of ggplot2 package can show us 3-dimensional graphs distributed according 3 factors in matrix form.
• In which we can see the anomalies occurs on which year and which region and which period.
• Here we investigate Energy versus default Energy balooned by Total Default Receivables according to region, year and period factors.
• Colors period, balloons Total Cash loans.

With this study we investigate NUTS 12 Regions credit loans performations by Graphical Datamining Analysis technique with a suitable software developed by us.
Dataset are factorized according to cities and years, sectorals and financial periods factors.
Periods: 2012-2014 accounts. Graphical Datamining applied on this factorized
data and financial anomalies dedected acording to time and space factors.
We observes apparently obvious differences of risk profiles affected by these factors
It is quite clear that pictures tells more stories than numbers
