Study Notes
Data Visualization
- Data visualization displays large quantities of data in a meaningful way to provide insights
- Improves decision-making, reduces reliance on IT professionals, and improves collaboration
- Tabular data can be used to identify exact values, but visual charts can show more complex relationships
Chart Types
- Column and Bar Charts: Compare values across categories, illustrate differences between sets of values, and show proportions
- Clustered Column Chart: Compares values using vertical rectangles
- Stacked Column Chart: Displays the contribution of each value to the total
- 100% Stacked Column Chart: Compares the percentage that each value contributes to a total
- Line Charts: Useful for displaying data over time, but can be difficult to interpret with greatly differing data values
- Pie Charts: Display the relative proportion of each data source to the total, but difficult to compare sizes of areas, limit categories, and use labels
- Area Charts: Combine features of pie charts and line charts, present more information, but can become cluttered with too many data series
- Scatter Charts: Show the relationship between two quantitative variables, require observations with pairs of variables
- Orbit Charts: A scatter chart where points are connected in sequence over time, showing the data's ‘path’
- Bubble Charts: A scatter chart where the size of the data marker corresponds to the value of a third variable
- Combination Charts: Display multiple data series on the same chart with different chart types, useful for comparing data with different scales
- Radar Charts: Show multiple metrics on a spider web, useful for comparing survey data or performance of different entities using the same criteria
- Stock Charts: Plot stock prices like daily high, low, and close
- Geographic Data: Highlight key data relationships, identify trends, and spot data errors
Other Visualization Tools
- Data Bars: Colored bars scaled to the magnitude of data values, placed directly within cells
- Color Scales: Shade cells based on their numerical value, also known as heatmap
- Icon Sets: Use various symbols to code data, like arrows or stoplight colors
- Sparklines: Graphics that summarize a row or column of data in a single cell
- Line Sparklines: Useful for time-series data
- Column Sparklines: Appropriate for categorical data
- Win/Loss Sparklines: Useful for data that moves up or down over time
Dashboards
- Visual representation of key business measures
- Provide summaries of key information to help manage business functions
