Let’s make data exploration clearer, one term at a time.


A

Term

Meaning

Ad Hoc Metrics

Custom metrics created on the fly in Explore. Great for quick, one-off calculations without saving to the dataset.

Alert

Notifies you when a chart meets specific conditions. Useful for monitoring KPIs like dips in signups or spikes in traffic.

Annotation

Notes added to charts to highlight events like product launches or holidays. Adds visual context to your data.

Area Chart

Area charts are similar to line charts in that they represent variables with the same scale, but area charts stack the metrics on top of each other.

B

Term

Meaning

Bar Chart

Used to show metrics as a series of bars. Excels at showcasing change over a dimension (e.g., time).

Big Number Chart

Showcases a single metric front-and-center. Big number is best used to call attention to a KPI or the one thing you want your audience to focus on.

Big Number with Time Period Comparison

Showcases a metric along with a comparison of value, change, and percent change for a selected time period.

Big Number with Trendline

Showcases a single number accompanied by a simple line chart, to call attention to an important metric along with its change over time or other dimension.

Box Plot

Also known as a box and whisker plot, this visualization compares the distributions of a related metric across multiple groups. The box in the middle emphasizes the mean, median, and inner 2 quartiles. The whiskers around each box visualize the min, max, range, and outer 2 quartiles.

Breakdowns

Provides a more granular view of the data in a waterfall chart, allowing you to understand not just the overall change, but also which specific categories or segments are contributing to that change.

Bubble Chart

Visualizes a metric across three dimensions of data in a single chart (X axis, Y axis, and bubble size). Bubbles from the same group can be showcased using bubble color.

C

Term

Meaning

Calculated Column

A custom column created using SQL. Lets you define new values (like “profit = revenue - cost”) within the dataset.

Calendar Heatmap

Visualizes how a metric has changed over a time using a color scale and a calendar view. Gray values are used to indicate missing values and the linear color scheme is used to encode the magnitude of each day's value.

Chart

A visual representation of your data, built in Explore. Can be saved and added to dashboards.

Chord Diagram

Showcases the flow or link between categories using thickness of chords. The value and corresponding thickness can be different for each side.

Dimension

A categorical field used to group or slice data (eg. product name, date, or region). Use to categorize, segment, and reveal the details in your data.

E

Term

Meaning

Embedded Dashboard

Force Refresh

Reloads the chart with fresh data, bypassing cached results. Helpful if you need real-time updates.

Funnel Chart

Showcases how a metric changes as the funnel progresses. This classic chart is useful for visualizing drop-off between stages in a pipeline or lifecycle.

G

Term

Meaning

Gauge Chart

Uses a gauge to showcase progress of a metric towards a target. The position of the dial represents the progress and the terminal value in the gauge represents the target value.

Generic Chart

Swiss army knife for visualizing data. Choose between step, line, scatter, and bar charts. This viz type has many customization options as well.

Graph Chart

Displays connections between entities in a graph structure. Useful for mapping relationships and showing which nodes are important in a network. Graph charts can be configured to be force-directed or circulate. If your data has a geospatial component, try the deck.gl Arc chart.

H

Term

Meaning

Handlebars

Write a handlebars template to render the data

Heatmap / Cohort Chart

Visualize a related metric across pairs of groups. Heatmaps excel at showcasing the correlation or strength between two groups. Color is used to emphasize the strength of the link between each pair of groups.

Histogram

The histogram chart displays the distribution of a dataset by representing the frequency or count of values within different ranges or bins. It helps visualize patterns, clusters, and outliers in the data and provides insights into its shape, central tendency, and spread.

I

Term

Meaning

Interactive Pivot Table

Used to summarize a set of data by grouping together multiple statistics along two axes. Examples: Sales numbers by region and month, tasks by status and assignee, active users by age and location. The chart allows for interactions such as column resizing, reordering, filtering, setting pivot columns, grouping rows and more within the pivot table itself.

Interactive Table

A raw records or aggregate table view of a dataset. The table allows for interactions such as column resizing, reordering, filtering, and more within the table itself.

J

Term

Meaning

Jinja

A templating language that allows dynamic SQL — like injecting variables, conditions, or filters.

L

Term

Meaning

Line Chart

Line chart is used to visualize measurements taken over a given category. Line chart is a type of chart which displays information as a series of data points connected by straight line segments. It is a basic type of chart common in many fields.

M

Term

Meaning

Metric

A numeric field or aggregation (like SUM or AVG) used to represent performance measures in charts.

Mixed Chart

Visualize two different series using the same x-axis. Note that both series can be visualized with a different chart type (e.g. 1 using bars and 1 using a line).

Physical Dataset

A table in a connected database.

Pie Chart

The classic. Great for showing how much of a company each investor gets, what demographics follow your blog, or what portion of the budget goes to the military industrial complex. Pie charts can be difficult to interpret precisely. If clarity of relative proportion is important, consider using a bar or other chart type instead.

Pivot Table

Used to summarize a set of data by grouping together multiple statistics along two axes. Examples: Sales numbers by region and month, tasks by status and assignee, active users by age and location. Not the most visually stunning visualization, but highly informative and versatile.
