{"version":"1.0","type":"rich","title":"Sequential Color Map with One Color","description":"This example visualizes light intensity across a narrow wavelength range of 620 to 630 nanometers using a sequential color map based entirely on shades of blue. The display is a horizontal strip of 11 adjacent blocks, where opacity increases with wavelength. The code uses plain JavaScript and the DOM API, creating each block via `document.createElement` and setting its background color through an `rgba` string with varying alpha values. No external libraries are required, and the mapping is linear, with intensity calculated from the wavelength difference.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16b19eab40b84782b46afe902ea02667?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
