Q1. What is the importance of data visualization?

Data visualization is reasonably important as it provides us a clear idea of the meaning of information by giving it visual context via maps or graphs. Therefore, it makes the data more natural for people to comprehend and hence makes it easier to identify patterns, trends, and outliers within large data sets.

Q2. What is data visualization?

Data visualization is basically the graphical representation of data and information. Subsequently, with the use of visual elements such as graphs, charts, and maps, data visualization tools give an accessible way of viewing and understanding outliers, trends, and patterns in data.

Q3. Mention the types of data visualization tools.

Some common types of data visualization tools are:

• Column Charts
• Bar Graphs
• Line Graphs
• Dual-Axis Charts
• Stacked Bar Graphs
• Pie Charts, etc.

Q4. What is metadata?

Well, metadata is the information that describes items in ArcGIS. When care is taken so as to provide good descriptions, one can find suitable items with a search and evaluate which of the items in the search results is the correct one to use.

Q5. What do you mean by filtering scheme?

Filtering is one of the major strengths of TIBCO Spotfire. It is the ability to filter your data that means we can control what data will be visible and used in calculations. Hence, we can show or hide data for particular categories, alter the time range to look at and step through a sequence of values one at a time, etc.

Q6. How can we create a new filtering scheme?

We can create the new filtering scheme by following the given steps:

1. Firstly, select Edit > Document Properties.
2. Then, go to the Filtering Schemes tab.
3. Click New.
4. At last, type a name and press OK.

Q7. Define the hierarchy filter.

A hierarchy filter basically shows the data in a hierarchy. This filter includes an expandable tree view, where the categories within several levels of the hierarchy are represented by checkboxes.

Q8. How do we create a checkpoint?

A checkpoint is manually generated with the help of the ActiveSpaces administration tool tibdg. Moreover, we can create periodic checkpoints using ActiveSpaces as well.

Q9. What is a waterfall chart?

A waterfall chart symbolizes the change in value after being affected by certain factors that increase or decrease the value. Then, the resulting value is presented.

Q10. Define a treemap.

A treemap is useful for displaying large amounts of data that can be structured hierarchically. It shows the data with the use of differently sized and colored rectangles. Thus, data in a treemap is organized hierarchically. Here, each branch in the hierarchy is represented by a rectangle, which in turn is divided into smaller rectangles that represent sub-branches. 

Q11. When do we group values?

There are times when a column in our data includes many categorical values, but some of them are not significant enough to be displayed as separate values. In this type of situation, we can group these values into a new categorical value.

Q12. What is the purpose of heat maps?

Heat maps are useful for the visualization of large amounts of multi-dimensional data and are used to identify clusters of rows with similar values, and are displayed as areas of the same color.

Q13. What options are available in the project data page?

Q15. What do you mean by logistic regression?

This is the classification method used when the Response column is categorical with two possible values only. The probability of the possible results is modeled with a logistic transformation as a weighted sum of the Predictor columns. Henceforth, the weights or regression coefficients are selected so as to maximize the likelihood of the observed data.

Q16. Define load balancing.

Load balancing can be defined as the efficient and methodical distribution of network or application traffic across several servers in a server farm. Hence, it ensures that no single server bears too much demand.

Q17. What is a classification tree?

This is a method of nonparametric classification that creates a binary tree by recursively dividing the data on the predictor values. The splits are selected so that the variation in the Response column is smaller in each child mode than in that of the parent node. Moreover, there are a variety of options that are used to control how deep the tree is grown.

Q18. What are connectors?

Connectors are used to connect Spotfire clients to an external system. They allow us to load and analyze data from, for instance, databases and data warehouses.

Q24. What does data manipulation refer to?

Data manipulation is the procedure of adjusting data so as to make it organized and comparatively easier to read and understand. Moreover, data manipulation language i.e. DML is a programming language that adjusts data by inserting, eliminating, and modifying data in a database so as to cleanse or map the data.

Q25. What is a feature layer?

A feature layer is basically a grouping of similar kinds of geographic features, like, buildings, cities, parcels, roads, and earthquake epicenters, etc. Moreover, these features can be points, lines, or polygons. These are most appropriate for visualizing data on top of the base maps.

Q26. What is a map layout?

The map layout is the assembling of the different elements of a map into a single whole, constituting the map itself, its legend, scale bars, title, and some other elements.

The property control dialog is useful for defining a control device in the text area that can alter the content of a property in a simple and easy way.

Q28. What is linear regression?

Linear regression models the numeric response column as a weighted sum of the predictor columns. The regression coefficients are selected by the method of least squares, hence, minimizing the sum of the squared differences between the observed response and the predictions based on the weighted sum.

Q29. What is shared data?

Shared data is the amount of data that is shared by many people on a single plan. Day by day, shared data plans are becoming increasingly rare as this is the age of unlimited data.

Q30. What is the purpose of layer properties dialog box?

The Layer Properties dialog box is different for various types of geographic data. Moreover, with the use of the Layer Properties dialog box, we can set the layer’s properties, like its symbology. Also, using a group layer, we can manage the properties which apply to the whole group.
