The demo used hardcoded pixel values for several plots which didn't scale with DPI, causing them to appear too small on high-DPI displays. Following ImGui's convention, this commit replaces hardcoded pixel values with ImGui::GetTextLineHeight() multiplied by appropriate factors. This ensures plots scale correctly with font size and DPI settings. Affected plots: - PolitiFact: Who Lies More? (400px -> 25*TextLineHeight) - Pie charts (250x250px -> 16*TextLineHeight square) - Heatmaps (225x225px -> 14*TextLineHeight square) - Scrolling/Rolling plots (150px -> 10*TextLineHeight) - DragRects/DragPoints plots (150px -> 10*TextLineHeight) - Drag and Drop plots (195px -> 13*TextLineHeight) This follows the same pattern used throughout ImGui's demo code for ensuring DPI-aware sizing.
