You can create a "Graphic Reference" scene for a given project in which you can preset the visual properties of your Experience.
We will review two options for this: Experience Layers and Design Accelerators
Using Experience Layers
First Method - Reuse content from an experience layer
If you know that your graphic chart will not change much and that you will reuse the same font styles or colors over and over, you could just create and add your style reference in an experience layer.
Right click at the Scene level and choose "Add a foreground experience layer".
In this foreground experience layer, add all of the content you want to always have available across your experience like a color swatch, texts for titles and/or paragraphs with specific font, size, style, or predefined shapes.
Once you added all of the elements you want, you will just need to copy and paste (or duplicate) them into a Scene from that experience layer.
Second Method - Using bindings to change all of your content dynamically
As explained above, consider one scene of your experience as a "Graphic Reference" scene in which you will have all the graphical parameters but this time you will use binding on these elements. When you change one property in the Graphic Reference scene, the properties of the assets all over your project will change as well, meaning you will spend less time editing different scenes of your experience (changing colors, fonts, etc.)
1) Create a new Scene and add an experience layer.
Add to this experience layer all of the content you want to dynamically change in your experience. Let's call this scene "Graphic Reference".
When ready, create another Scene and duplicate the Graphic Reference content to that new Scene.
2) This new Scene will serve as a template for all your next scenes.
First, exclude the experience layer from the "Template" Scene.
Then start by Binding your elements in the "Template" Scene to the assets located in the experience layer of the "Graphic Reference" scene.
3) After binding all the elements you want to dynamically change, create as many Scenes you need in your project by duplicating the "Template" scene.

Using Design Accelerators
If you plan to reuse the same company branding over multiple projects, then Design Accelerators could be of great help.
With Design Accelerators, you are able to create your own style of Assets, Collections or even entire Scenes and reuse them as much as you want. The goal here is to help you speed up the experience creation.
