Visualizing Data for Non-Data Experts: Making Reports Accessible to All
summary
Shows a real failure case: a 25‑page vessel‑tracking Power BI report managers and captains cannot use, then a redesign that removes noise and surfaces action‑ready insights. Covers concrete Power BI features: Ctrl+Shift+F11 (table view), keyboard navigation and how to reorder the tap order in half a minute, using DAX for dynamic titles, adding meaningful alt text (max 250 chars), high‑contrast and color‑blind checks, reset‑filters button and conditional formatting to make tables readable. Practical steps that make reports actually usable by non‑data experts.
