Research Poster - The Lead Impacted Child and Learning

I am presenting to a cohort of beginning doctoral students in education. My research poster will be a minimum of 36" x 48" and no more than 42" x 48". I am showcasing my own research and I have all content written. I am including several charts - I have completed them on Canva, but I have no clue how to export them into my poster template. I will need to have an eye-catching color palette and specific size requirements for the fonts used. I'm including an example of a poster that I like and can serve as a guide. I can send along the specifics for font, and headings to be included. Thank you!
