Write a Tableau style guide for [TEAM]. Brand colours: [COLOURS]. Common chart types we use: [CHART_TYPES]. Problems seen in current dashboards: [PROBLEMS]. Audience needs: [AUDIENCE_NEEDS]. Write numbered rules, each testable by a reviewer and with a good and a bad example in words. Cover palettes for categorical, sequential and diverging data and when to use each, status colours, colour-blind users, font sizes, titles (what, compared with what, over what period), axis and number formats, tooltips, null handling, sort order, annotations, and chart choice with a table of Question, Chart type and Avoid (bar, line, scatter, table, map; no 3D, no pie with many slices, no dual axes without clear labels), plus a one-line rule for each chart type. Use hex codes only for brand colours I supplied, mark features such as palette files [VERIFY], and provide a ten-point review checklist with a peer review step before publication. Keep the guide short enough to read in ten minutes, and say which five rules matter most if people only follow a few. Put the examples in words so the guide works without screenshots.
