Unleash full power of built-in Power BI visuals, create custom IBCS-styled charts using DAX only!

Earlier in 2023, the ability to customize the width and height of SVG images in the Matrix and Table visuals was introduced, along with a New Card visual that supports SVG images.

Andrzej Leszkiewicz will demonstrate how these features can be leveraged to create advanced custom data visualizations without the need for custom Power BI visuals.

Andrzej will show how to transform a lackluster and ineffective matrix or table into a highly effective data visualization. He will cover how to embed multiple charts into a table or matrix and how to format the visualization in accordance with the International Business Communication Standards (IBCS) guidelines.

You'll learn how IBCS-styled data visualizations improve the interpretability of data visualizations and how to incorporate them into your reports without paying for custom visuals licenses, using only core visuals and open-source solutions based on DAX and SVG.

You'll learn how a single DAX measure can be used to generate a chart (SVG image) that can be used as a standalone chart or can be embedded into a cell of a table or matrix as part of a larger data visualization such as a small multiple.

You'll learn how to use calculation groups to make DAX code that generates SVG charts reusable - only one instance of DAX code is required to generate multiple charts of the same type.

To participate in this session, you don't need to know what IBCS is, but intermediate understanding of DAX is advised; variables, calculation groups, and CALCULATE, CALCULATETABLE, FILTER, HASONEVALUE, SELECTEDVALUE, ALLSELECTED, SWITCH, ADDCOLUMNS, MINX, MAXX, AVERAGEX, DIVIDE, ROUND, ABS, SELECTEDMEASURE, SELECTEDMEASURENAME functions are used. Basic understanding of SVG images (rect, line, text elements are used) will be useful.

It's going to be my first session as a speaker (not taking into account a session I delivered 15 years ago, on a different topic, on-site event, 300+ attendees).

IBCS-guided charts with Just Core Power BI Visuals and DAX

Andrzej will show how to transform a lackluster and ineffective Power BI matrix or table into a highly effective data visualization. He will cover how to embed visualizations into core Power BI visuals (Table, Matrix, Button slicer) and how to format them in accordance with the International Business Communication Standards (IBCS) guidelines.

This session is aimed at Power BI report developers who want to learn how International Business Communication Standards (IBCS) can enhance the interpretability of Power BI reports and how to apply them in Power BI without using custom visuals.

An intermediate understanding of Power BI core visuals and DAX is recommended. You do not need prior knowledge of IBCS. However, you can attend another Andrzej session to gain a better understanding of what IBCS is and why it is beneficial for reports and dashboards.

Highly Customized Power BI Visualizations with Deneb and Vega

Andrzej Leszkiewicz is a creator of highly customized and interactive data visualizations using Vega visualization grammar and Deneb custom visuals for Power BI. Andrzej will demonstrate how Deneb and Vega can be leveraged to create advanced custom data visualizations.

Target Audience:

Power BI report developers eager to learn how to create custom data visualizations without learning JavaScript and Power BI visuals SDK. Vega visualization grammar is a declarative language that is relatively easy to learn (it's just a JSON file that describes all visual elements).

Session Level and Prerequisites:

Advanced. If you've already realized that core Power BI visuals limit your data storytelling ideas and you haven't found any existing custom visual that satisfies your requirements, it's time to start using Deneb. Understanding of the JSON format is recommended, and a basic understanding of any programming language will be useful.

Learning Objectives:

You'll learn what kind of possibilities the Deneb custom visual for Power BI and Vega visualization grammar offer and how they can be used to move your data visualization far beyond the limitations of Power BI core and many existing custom visuals. You'll learn how to create simple charts using dozens of Deneb Vega templates, and you'll see how further learning of Vega can help you in creating highly customized data visualizations.

Examples of my Deneb/Vega visualizations:

Deneb Templates: https://github.com/avatorl/Deneb-Vega-Templates/tree/main

Complete report created using a single instance of Deneb: https://powerofbi.org/hr-cross-functional-mobility-rwfd/

Various Vega visualizations: https://powerofbi.org/deneb-vega-data-visualization-examples/

Creating a dashboard using only one visual (Deneb)

In this session, the speaker demonstrates how a single instance of the Deneb custom visual can be leveraged to create an entire report page (dashboard), not just a single chart. This method enables the development of highly customized charts while also facilitating advanced interactions between charts, such as cross-filtering and cross-highlighting.

The presentation shows that creating "highly customized" charts doesn't have to mean making them overly complex or ornamental. Instead, it often involves deep customization to ensure that simple bar charts and heatmaps work together effectively, enhancing data exploration and understanding for end users.

Target Audience:

This session is designed for data visualization professionals who struggle to build comprehensive Power BI reports using various visuals, unaware that a possible solution is to use just one. This session is not for beginners looking to learn how to build their first Power BI reports.

Session Level and Prerequisites:

Intermediate. While a basic understanding of the Deneb custom visual and Vega or Vega-Lite languages is helpful, it is not required. This session may serve as inspiration to start learning them. Instead of a deep dive into "how" (advanced Vega coding), the speaker explains "what" he did and "why" to build this dashboard.

Learning Objectives:

The Real Power of the New Slicers: Turn Your Slicers into Charts

This session will show you how to take your Power BI reports to the next level by turning charts into interactive slicers. Using the new native slicer visuals, you'll learn how to create slicers that not only filter your data but also display it. Think bar and column charts, maps, or any custom data visualizations, all acting as slicers.

These slicers aren’t just clickable visuals. They support all the features you'd expect from a slicer, like row/column/grid layout; custom formatting for Rest, Hover, Press, and Selected states; default and persistent selection; synchronization across pages; and paginated or continuous scroll overflow.

But instead of using text-based buttons or static images, you will use visuals packed with context to make sure report users don't waste their time randomly selecting contextless slicer items. They will slice for a reason. For example, a user might select a customer because a red variance bar indicates a year-over-year drop in sales, or choose another customer because the bar chart shows they had the highest sales in the previous year.

Who should attend

Power BI report creators, data analysts, and anyone looking to make their reports more interactive and helpful.

Session Level and Prerequisites

Intermediate. You should already be comfortable creating simple Power BI reports, working with native slicers, and writing basic DAX (think VAR, RETURN, CALCULATE, SUMX, CONCATENATEX, SWITCH, ALLSELECTED and so on).

Attendees will learn:

➡️ How to help report users slice for a reason
➡️ How to turn native slicers into interactive charts
➡️ How to use DAX to generate charts (as SVG images)
➡️ How to apply this approach to different chart types, including column charts, bar charts, and maps
➡️ How to add meaning and context to your slicers
➡️ How to improve the appearance and functionality of the slicers

Deep dive into customizing core visuals for clarity and impact

In recent years, Power BI expanded SVG support in Table, Matrix, Card, and Image visuals, as well as Button and List Slicers. Andrzej Leszkiewicz shows how to use SVGs to customize core visuals for clarity and impact. The goal of this customization is not to decorate, but to streamline and unify BI reports.

You'll learn how to build IBCS-guided reports for clearer business insights (IBCS: International Business Communication Standards, see also ISO 24896 Notation for business reporting); how to embed charts into P&L reports; how to turn charts into slicers and slicers into charts; how to make a Top N + Others bar chart without any changes to the data model; and other ways to improve your reports.

With user-defined functions (UDFs) introduced in 2025, report unification through customization is easier than ever. Free open-source UDF libraries let you embed charts into the core visuals just by calling a function.

Take your Power BI visuals to the next level in this hands-on deep dive!
