Online Resources

Power BI, Copilot for Power BI, Microsoft Fabric, and the wider data-visualization community • Last verified 2026-06-24

This is the living index of online resources cited in The Defensible Decision, organized by purpose. Every URL on this page was reached and reviewed on the verification date at the top; the per-section date stamp tells you when each block was last walked end-to-end. URLs change, sites move, and vendor documentation reorganizes itself constantly — when print and this page disagree, this page wins, because the web changes faster than reprints.

The page is split into three layers: first-party Microsoft sources (the canonical documentation, blogs, certifications), third-party Power BI and Copilot community resources (the practitioner sites, tooling, and forums that built the Power BI ecosystem), and the wider data-visualization community (the books, blogs, and conferences that ground the principles Part I of the book teaches).

1. The book's own living resources

The two places on this site where the book's deferred-to-online material lives. The Chart Gallery is the source of truth when it disagrees with the print Appendix E; the Appendix E resources index is the only place that hosts the BRD template, the starter BRDs, and the AIRS exemplar in editable form.

Resource URL What it covers
Chart Gallery (living catalog) thedefensibledecision.com/gallery Forty-eight chart types organized by analytical intent. The static print snapshot is Appendix E; the online gallery is the source of truth when the two disagree.
Appendix E resources index thedefensibledecision.com/appendix-e The BRD template, the four starter BRDs, the worked AIRS exemplar, and the three elicitation prompts from Appendix E § Section 2.
Appendix F statistics claim check thedefensibledecision.com/statistics/ Claim checks, worked examples, and a synthetic Excel workbook for reading averages, differences, associations, and AI-generated drivers without overclaiming.

2. First-party — Power BI & Fabric documentation

The canonical living documents for the products this book teaches you to direct. When the book stays at the strategic level and tells you "see the Microsoft docs for the syntax," this is where to go.

3. First-party — Copilot for Power BI

The Copilot-specific documentation: the introduction page, the create-reports surface where the CSAR loop applies, the Prep-for-AI configuration that Chapter 11 frames strategically, and the four AI visuals Chapter 10 covers individually. These are the pages cited inline throughout Part II of the book.

5. First-party — certifications and training paths

When a reader wants to go deeper than the book takes them, these are the routes. The book deliberately stays at the strategic / directional level; Microsoft Learn carries the syntax, the modeling depth, the admin configuration, and the exam preparation.

Credential or course URL Who it's for
PL-300: Microsoft Power BI Data Analyst Associate learn.microsoft.com/credentials/certifications/data-analyst-associate The Power BI practitioner credential. Covers data prep, modeling, DAX, visualization, deployment.

6. Third-party — Power BI practitioner sites

The Power BI ecosystem has been carried for years by a small set of practitioner-authors. These are the most-cited third-party voices on DAX, modeling, M / Power Query, and (increasingly) Copilot. They are not Microsoft, but Microsoft frequently links to them and many of the authors are Microsoft MVPs.

Site (author) URL What it covers
SQLBI (Marco Russo, Alberto Ferrari) sqlbi.com The reference site for DAX and Tabular modeling. Free articles, paid courses, and the published DAX / Definitive Guide to DAX book series.
DAX Patterns (SQLBI) daxpatterns.com A pattern catalog of reusable DAX solutions, organized by analytical intent. The companion to the SQLBI patterns book.
RADACAD (Reza Rad) radacad.com Long-running Power BI training and consulting blog. Strong coverage of Power Query / M, Power BI Service administration, and Fabric.
Guy in a Cube (Adam Saxton, Patrick LeBlanc) guyinacube.com · YouTube channel Weekly Power BI and Fabric video updates from two senior Microsoft engineers, published independently. Often the fastest source for what changed in the latest release.
Curbal (Ruth Pozuelo Martinez) curbal.com Power BI tutorials, DAX walkthroughs, and a popular YouTube channel for technique-by-technique deep dives.
Power BI Tips (Mike Carlo, Seth Bauer) powerbi.tips Tutorials, a theme generator, and the Explicit Measures podcast. Useful for visual-design conventions and report-page composition.

Verified 2026-06-24. This list is intentionally short — the authors named here are widely cited across the Power BI community and have track records measured in years. There are many more practitioner blogs; we list the ones we have personally verified as reliable references.

7. Third-party — Power BI community tooling

The community-built tooling that augments what Power BI Desktop ships with. Several of these are routinely cited in Microsoft's own documentation as the way to do specific tasks that the Desktop UI does not cover.

Tool URL What it does
DAX Studio daxstudio.org Open-source DAX query editor and profiler. The standard tool for testing and optimizing DAX measures outside Power BI Desktop.
Tabular Editor tabulareditor.com Tabular model editor (version 2 free / open-source; version 3 commercial). Used to edit semantic models beyond what the Desktop UI exposes.
Bravo for Power BI bravo.bi Free companion that ships time-intelligence DAX, model documentation, and analyze-model reports.
ALM Toolkit alm-toolkit.com Compare and deploy Power BI datasets across environments. Useful for treating semantic models as code (source control, diff, promotion).

Verified 2026-06-24.

8. Third-party — community forums & user groups

When you hit something neither the book nor Microsoft Learn explains, these are where to ask.

Community URL Notes
Microsoft Fabric Community community.fabric.microsoft.com The official Microsoft community. Includes Power BI and all Fabric workloads. Tag your questions by workload.
Power BI subreddit reddit.com/r/PowerBI Practitioner-to-practitioner help, often faster turnaround than the official forum for common problems.
Stack Overflow — powerbi tag stackoverflow.com/questions/tagged/powerbi For specific DAX, M, and Power Query problems.
Power BI User Group (PUG) pbiusergroup.com Global network of local Power BI user groups. Search for a chapter in your city; many run monthly hybrid meetings.

9. Wider data viz — open-access companion books

Free, online, complete-manuscript versions of practitioner books. Several have a print edition listed in Appendix C; the online version cited here is the open-access companion. Use them as searchable reference material for the principles Part I of The Defensible Decision teaches.

Title and author URL What it covers
Wilke, C. O. — Fundamentals of Data Visualization (online edition) clauswilke.com/dataviz Full open-access manuscript of the O'Reilly print book listed in Appendix C. The directory of visualizations chapter is a strong reference for chart-type selection.
Healy, K. — Data Visualization: A Practical Introduction (2nd ed. online draft) socviz.co Complete draft of the Princeton University Press 2026 second edition. R / ggplot-focused, but the principles chapters transfer to any tool.
Wickham, H., Cetinkaya-Rundel, M., & Grolemund, G. — R for Data Science (2nd ed.) r4ds.hadley.nz The R / tidyverse handbook. Out of scope for this book's Power BI focus, but a strong reference for readers who pair Power BI with R or Python for prep.

Verified 2026-06-24.

10. Wider data viz — practitioner websites

The places working data-visualization practitioners go for examples, makeovers, and templates.

Site (author) URL What it offers

How to use this page

If you spotted a dead link, search the parent site for the new location; vendor documentation almost always preserves the content somewhere when it moves a URL. If the resource is genuinely gone, file an errata report and we will retire the entry on the next verification pass.

This page is re-verified end-to-end on a quarterly cadence and at every major book revision. The verification date at the top of the page is always the most-recent end-to-end pass; per-section dates reflect when each block was last walked.
