Tableau Maps and Geographic Views

Tableau builds maps automatically when your data contains geographic fields like Country, State, City, or Zip Code. Maps turn location-based data into a visual that reveals patterns no table or bar chart can show — like which states have the highest sales or which cities have the most customers.

How Tableau Recognizes Geographic Fields

Tableau scans your data for fields that match known geographic names. Fields recognized as geographic get a small globe icon in the Data Pane. Common examples include Country, State/Province, City, Postal Code, and Latitude/Longitude pairs.

Diagram: Geographic Field Recognition

Data Pane Fields:
  🌐 Country         ← Globe icon = geographic
  🌐 State
  🌐 City
  🌐 Postal Code
  Abc  Product Name  ← No globe = not geographic
  #    Sales         ← Number = measure

Building Your First Map

Double-click the State field in the Data Pane. Tableau places it on the Rows and Columns shelves automatically and draws a map of the United States with each state highlighted. No extra steps needed. Drag Sales to the Color box in the Marks Card and the map colors each state based on total sales — darker shade means more sales.

Step-by-Step: Choropleth Map (Color-Filled Map)

1. Double-click State (Tableau draws the base map)
2. Drag Sales to the Color box in the Marks Card
3. Tableau fills each state with a color based on SUM(Sales)
4. Click the Color box to change the color palette

United States Map:
+------------------------------------------+
|                                          |
|   [light]  [dark]  [medium]              |
|   Oregon   Texas   Florida               |
|   $400K    $1.2M   $700K                 |
|                                          |
|  Color legend: Light = Low  Dark = High  |

Symbol Map (Bubble Map)

A symbol map places circles on locations instead of filling entire regions. Circle size shows magnitude — a bigger circle means a larger value. Symbol maps work better than filled maps when your data has many closely spaced locations like cities.

Building a Symbol Map

1. Drag City to the canvas (Tableau draws a map)
2. Change the Marks type dropdown from "Map" to "Circle" or check Show Me for the symbol map option
3. Drag Sales to Size in the Marks Card — circles grow larger for higher sales
4. Drag Profit to Color — colors circles by profit (green = profitable, red = loss)

Diagram: Symbol Map

+-------------------------------------------+
|          * Seattle (large circle)         |
|                                           |
|  * Portland                               |
|  (medium)                                 |
|                    ** Chicago             |
|                    (very large)           |
|                                           |
|          * Denver (small circle)          |
+-------------------------------------------+
Circle size = Sales total
Circle color = Profit (green/red)

Map Layers and Background

Tableau maps use an online map background by default. You can change or customize this background. Go to Map menu → Map Layers. Toggle streets, terrain, coastlines, country borders, and city names on or off. Choose Offline or different map styles if needed.

Filtering on Maps

Maps support all standard filter types. Drag Region to the Filters shelf and select specific regions. The map zooms and updates to show only those areas. You can also draw a selection box directly on the map by holding Ctrl and dragging — this filters to only the geographic area you drew.

Latitude and Longitude Data

When Tableau cannot recognize a location name — for example, a custom location like a store branch name — you supply Latitude and Longitude columns yourself. Assign the Latitude field to Rows and the Longitude field to Columns. Change the Marks type to "Circle." Tableau plots exact points at each coordinate pair.

Custom Location Example

Store Name    | Latitude  | Longitude
Mumbai Store  | 19.0760   | 72.8777
Delhi Store   | 28.6139   | 77.2090
Pune Store    | 18.5204   | 73.8567

→ Tableau plots three dots on the map
  at the exact coordinates of each store

Proportional Symbol Map with Labels

Drag City to Detail in the Marks Card, Sales to Size, and the City name to Label. Now every bubble on the map shows the city name alongside it. This is useful when presenting to an audience unfamiliar with geography.

Map Tooltips

Hover over any bubble or region on a Tableau map and a tooltip appears. Tableau shows the location name and the values of any Measures you added to the view. Click the Tooltip box in the Marks Card to customize the tooltip text — add context, bold numbers, or plain text explanations.

When to Use Maps vs Other Charts

Summary

Tableau detects geographic fields automatically and builds maps with a double-click. Filled maps color entire regions by value. Symbol maps use bubble size and color to show two measures at once. Custom latitude and longitude data lets you map any location Tableau does not know by name. Maps filter and interact just like any other chart type — drag fields to Color, Size, Label, and Tooltip to add layers of meaning.
