This is the living index of tool-agnostic resources cited in The Defensible Decision. 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.
Use the Power BI, Fabric, and Copilot section for product documentation, training, community tooling, and setup guidance. This page keeps the wider data-visualization references that support the principles in Part I regardless of the platform a reader uses.

1. Maintained companion resources
The four resources on this site hold material that benefits from being updated after print. The Chart Gallery is the current chart catalog when it differs from the print Appendix D. Death by Pie Chart is a reusable visual companion to its anti-pattern lesson. The Appendix E resources index hosts the BRD template, starter BRDs, and worked exemplars in editable form. Appendix F provides the statistics claim check.
| Resource | URL | What it covers |
|---|---|---|
| Chart Gallery (living catalog) | thedefensibledecision.com/gallery/ | Forty-one chart cards organized by analytical intent. The static print snapshot is Appendix D; use the online gallery for current examples and implementation notes. |
| Death by Pie Chart | thedefensibledecision.com/death-by-pie-chart/ | A reusable arcade title-slide animation that turns the book's pie-chart anti-pattern into a visual opening for talks and workshops. |
| Appendix E resources index | thedefensibledecision.com/appendix-e/ | The BRD template, four starter BRDs, five completed exemplars, and three elicitation prompts from Appendix E §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. 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. |

3. Wider data viz — practitioner websites
The places working data-visualization practitioners go for examples, makeovers, and templates.
| Site (author) | URL | What it offers |
|---|---|---|
| Storytelling with Data (Cole Nussbaumer Knaflic) | storytellingwithdata.com | Blog, makeovers, chart guide, podcast, YouTube channel, paid workshops. The active publishing arm of the Storytelling with Data book series. |
| Perceptual Edge (Stephen Few archive) | perceptualedge.com | Archive of Few's articles from 2003–2017 (no longer actively updated, but the writing remains foundational on dashboard design and visual perception). |
| The Functional Art (Alberto Cairo blog) | thefunctionalart.com | Cairo's writing on journalism-grade visualization; useful complement to the business-analytics framing this book emphasizes. |
| Visualising Data (Andy Kirk) | visualisingdata.com | Kirk's blog and chart-resource library. The companion to his Data Visualisation handbook. |
| FlowingData (Nathan Yau) | flowingdata.com | Long-running practitioner blog. Useful for chart examples and critique; treat as inspiration, not authority. |
| Information is Beautiful (David McCandless) | informationisbeautiful.net | High-design infographic gallery; useful for seeing what's possible at the editorial-illustration end of the spectrum. |

4. Wider data viz — research & academic resources
Conferences and proceedings where current visualization research lives, for readers who want the academic-side depth.
| Venue | URL | Field |
|---|---|---|
| IEEE VIS conference | ieeevis.org | The premier visualization research conference. October each year. Proceedings on IEEE Xplore. |
| ACM CHI conference | chi.acm.org | Human-Computer Interaction; many visualization papers, with broader interaction context. |
| Visualization Resources (compiled by Tamara Munzner) | cs.ubc.ca/~tmm/vadbook | Companion resources to Munzner's Visualization Analysis and Design (Appendix C). Lecture slides, exercises, references. |

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.
