What Makes MongoDB Charts Unique?
Before we dive into the details, it‘s important to understand what sets MongoDB Charts apart from traditional business intelligence tools.
Here are three key advantages:
Native Integration with MongoDB
MongoDB Charts is built directly into MongoDB Atlas and can connect directly to your clusters. This means:
- No lengthy ETL process required to move data elsewhere
- Real-time dashboards and visualizations as data changes
- Leverage existing MongoDB roles and permissions for access control
By natively integrating Charting capabilities directly into MongoDB, it solves major pain points around optimizing data for visualization.
Document Data Model Flexibility
SQL databases require rigid tabular structures. But MongoDB‘s document model gives you the flexibility to store data in whatever schema makes the most sense for your application.
MongoDB Charts is designed to handle flexible schemas with nested objects and arrays much more gracefully than old-school BI tools.
You don‘t have to reshape your data just for the sake of charting. Charts can handle it as-is!
Simplicity and Ease of Use
MongoDB Charts uses an intuitive drag-and-drop interface to let you construct charts visually:
With just a few clicks, you can:
- Select data sources
- Assign field mappings
- Apply filters
- Switch chart types
- Customize styles and colors
This simplifies what is often a labyrinthine process into something anyone can manage.
These design advantages add up to a uniquely powerful yet easy-to-use charting experience. You get flexibility AND simplicity.
Now let‘s dive into how to get started…
Step-by-Step Guide to Enabling MongoDB Charts
MongoDB Charts is included with MongoDB Atlas, but you need to take a couple steps to enable it:
Step 1) Create an Atlas Account
Head to https://www.mongodb.com/cloud/atlas/register and create an account if you don‘t already have one.
Step 2) Deploy a Free Atlas Cluster
Follow the prompts to deploy a free shared cluster. Select the cloud provider and region you prefer.
Step 3) Load Sample Data (Optional)
For easy testing, click "Load Sample Dataset" on the cluster overview page to quickly add sample collections.
Step 4) Open the Charts Module
In the left nav bar of Atlas, click on the Charts icon to open the Charts workspace.
Step 5) Create Your First Chart
Charts will provide a brief tutorial for creating your first simple chart against the sample data.
And that‘s all there is to it! Atlas will automatically handle deploying and configuring Charts on your cluster.
Now you‘re ready to start building visualizations against your live databases.
Let‘s explore how to construct charts using the builder interface…
Creating Charts with the MongoDB Charts Builder
The Charts builder provides a clean drag-and-drop workspace for designing your visualizations.
Here‘s an overview of the key components:
A. Data Source Panel – Select the cluster, collection, or CSV data you want to chart.
B. Chart Types Panel – Choose from 10+ visualization types like bars, lines, pies, etc.
C. Fields Panel – Drag and drop fields here to define axes and data bindings.
D. Encoding Panel – Map fields to visual properties like X, Y, color, size.
E. Filter Panel – Filter data before visualizing it.
F. Customization Panel – Adjust visual settings like colors, labels, tooltips.
G. Query Panel – Shape data using aggregations before charting.
H. Preview Panel – Watch your chart update in real time.
With these intuitive panels, you can construct even complex visualizations with just a few clicks and drags. No coding required!
Let‘s walk through building a sample chart step-by-step:
1. Choose Data Source
I‘ll select a restaurants collection containing data on restaurants in various cities.
2. Pick Chart Type
I‘ll use a vertical bar chart to compare ratings across restaurant types.
3. Map Fields to Encodings
I‘ll drag city to the X-axis and rating to the Y-axis.
4. Customize Styles
I‘ll tweak colors, tooltips, and axis labels.
5. Apply Filters
I‘ll filter to just Chinese cuisine restaurants.
6. Preview the Final Chart
My customized vertical bar chart shows average Chinese restaurant ratings by city!
With these six simple steps, I created a polished interactive chart without writing any code.
Next let‘s explore the wide variety of chart types available.
MongoDB Charts Types Explained
MongoDB Charts supports a comprehensive set of visualization types.
Each chart serves a different analytical purpose. Here‘s an overview of the options:
Column Charts
Column charts compare values across a limited set of categories. Use them when you have shorter text labels.
Bar Charts
Bar charts also compare values across categories. Use bar charts when category labels are lengthy.
Line Charts
Great for visualizing trends and changes over time. Lines connect sequential data points.
Area Charts
Area charts fill the space below a line, emphasizing volume and degree of change.
Pie Charts
Displays proportional comparisons across categories. Pie slices represent values.
Donut Charts
Just like pie charts but hollow in the center, allowing for labels.
Scatter Plots
Plots correlations between two numeric variables. Shows clustering.
Bubble Charts
Similar to scatter plots but with a third data dimension mapped to bubble size.
Heatmaps
Great for spotting trends and patterns in dense datasets. Color coding emphasizes intensity.
Geospatial Charts
Plot points onto geographic maps using latitude/longitude coordinates.
Funnel Charts
Illustrate sequential stages in a process with cascading flows.
Text Charts
Format and display rich text, markdown, links, and images in a chart.
This chart type palette gives you diverse options to explore your data from every angle.
Now let‘s discuss how to combine charts into shareable dashboards.
Creating Beautiful Data Dashboards in MongoDB Charts
While individual charts are useful, often you‘ll want to assemble collections of charts into dashboards to share deeper insights.
Benefits of Dashboards
Well-designed dashboards empower users to:
- Identify trends across multiple metrics
- Interact with filters to slice and dice data
- Explore data visually without coding skills
- Understand key takeaways at a glance
- Make faster, more informed decisions
Here are some best practices for creating effective MongoDB Charts dashboards:
Combine Related Charts
Group charts covering connected metrics together into rows or tabs. This makes comparison easy.
For example, sales managers might want to see:
- Regional revenue
- Regional profit
- Regional expenses
Grouped together on one tab.
Pick Coherent Visual Types
Use consistent chart types across your dashboards for clarity. For example, always use line charts for trends over time.
Include Text and Labels
Text charts allow you to annotate your dashboards with explanations, insights, instructions, etc.
Add Interactive Filters
Let users narrow down the data by specific criteria to surface insights.
Curate Select Key Metrics
Dashboards shouldn‘t try to visualize every possible metric simultaneously. Pick a focused set of 3-5 key metrics to avoid clutter.
Refine Iteratively
Tweak and adjust until the data story is crystal clear. Enlist stakeholders to give feedback.
Simplify Sharing
Use view-only links and embeds so other users can interact without a MongoDB account.
Applying these dashboard design principles will maximize their value for driving data-informed decisions.
Next let‘s explore collaboration features.
Collaboration Features
MongoDB Charts offers excellent capabilities for cooperating on dashboards:
Comments
Annotate charts and dashboards with threaded conversations and commentary.
Notifications
Get notifications when someone edits or interacts with your charts.
Present Mode
Hide construction panels for clean, distraction-free dashboard viewing.
Granular Permissions
Control edit vs view access on dashboards and charts individually.
Public Sharing
Open up dashboards to anyone with a simple public link.
Embedding
Embed live read-only dashboard views into webpages.
Exports
Download as PDFs or CSV data for offline analysis.
These collaboration tools make it a breeze to discuss and share insights as a team.
Now let‘s talk about best practices for structuring your data for maximum charting value.
Designing Your Data for Peak MongoDB Charts Performance
MongoDB‘s flexible document model makes it easy to evolve your schemas rapidly. But for peak charting value, a bit of upfront model optimization goes a long way.
Here are some tips for structuring your data with MongoDB Charts in mind:
Flatten Nested Structures
MongoDB Charts can only map top-level fields visually. Flatten nested objects when possible.
Standardize Field Names
Use a consistent naming convention like cityPopulation not CityPop for clarity.
Unify Similar Fields
Don‘t mix cost, price, and value. Standardize on one preferred term.
Add Unique Identifiers
Include fields like customerID to enable joins/lookups during analysis.
Model Time Series Cleanly
Store dates, timestamps, and periods consistently to chart trends.
Limit Array Nesting
Deep nested arrays are difficult to chart – keep flattened when possible.
Index Charting Fields
Add indexes on fields used for axes, filters, and tooltips to optimize performance.
While MongoDB affords tremendous schema flexibility, taking the time to intentionally model your data will pay dividends when visualizing it later.
Now let‘s dive into limitations of the free tier.
MongoDB Charts Limits in the Free Tier
The MongoDB Charts free tier has the following constraints:
- Only shared clusters eligible (not dedicated M0+ tier)
