In this chapter, we focus on visualizing proportions of a whole; we see that pie charts really aren't so bad, along with discussing the waffle chart and stacked bars for comparing multiple proportions.

Grammar of Graphics intro

Familiarizing with disease data

Warming up data-wrangling

The pie chart and its friends

The infamous P-I-E

Cleaning up the pie

How about a waffle?

When to use bars

Basic stacked bars

Ordering stack for readability

Categorical x-axis

Proportions of a whole

We shift our focus now to single-observation or point data and go over when bar charts are appropriate and when they are not, what to use when they are not, and general perception-based enhancements for your charts.

Point data

We now move on to visualizing distributional data, we expose the fragility of histograms, discuss when it is better to shift to a kernel density plots, and how to make both plots work best for your data.

Importance of distributions

Orienting with the data

Looking at all data

Changing y-axis to density

Histogram nuances

Adjusting the bin numbers

More bars

Bin width by context

The kernel density estimator

Histogram to KDE

Putting a rug down

KDE with lots of data

Single distributions

Finishing off we take a look at comparing multiple distributions to each other. We see why the traditional box plots are very dangerous and how to easily improve them, along with investigating when you should use more advanced alternatives like the beeswarm plot and violin plots.

Intro to comparing distributions

Kursus ini akan membantu Anda melampaui dasar-dasar visualisasi data dan mengasahnya menjadi bagian yang kuat dari perangkat data science Anda. Sepanjang pelajaran, kita akan menggunakan dua himpunan data terbuka yang menarik untuk membahas berbagai jenis data (proporsi, data titik, distribusi tunggal, dan beberapa distribusi) serta meninjau kelebihan dan kekurangan visualisasi yang paling umum. Selain itu, kita akan membahas beberapa alternatif visualisasi yang kurang umum untuk jenis data tersebut dan cara menyesuaikan pengaturan bawaan ggplot agar pesan Anda tersampaikan dengan paling efisien dan efektif.
