Yes for lab reports and poster boards if axes, units and a source line are present. Excel or Google Sheets or PowerPoint; export SVG/PDF. Do not rely on hue alone. Label directly and check greyscale. Histogram: honour count of observations inside each bin, and switch when bins differ in width, or you are comparing named categories.
The core mark of Histogram is count of observations inside each bin. one continuous measurement and its shape The eye compares length and position more accurately than area.
