1. Choose your level of analysis.

In many instances you will find data arranged in hierarchical manner depending by the nature of institution. For retail sector, this could be from product category to product sub-category to products. Or County to District to Location to Sub location for Country administration data. As a developer, it’s good to understand the level your persona will be interested and build your story just on that level. If your persona’s interest lies in the whole data, the best approach is to build your analysis at the course level (County for administration data) but still enabling users to drill down to fine level data (Sub-location data).

A good example is this dashboard on population and internet user’s statistics in Africa 2018. Users can view metrics at continent level and drill down to specific countries of choice.

2. Choose the right charts and graphs.

With a good understanding of the level of analysis, it’s important to select charts or graphs which presents your data insights visually well. A good example to related with, is when telling a story on distributions of data, a box plot and histogram will be the first charts to think of. But, be assured the two charts may not be equally suitable for your data at hand, that’s why it good to test the two and chose the most suitable chart. It is also advisable to test how your chart behaves when data is sliced to lower levels with fewer data points.

3. Avoid unnecessary marks.

Space is critical in dashboard building process, and therefore anything that features in your dashboard MUST add value. A good example on instances where unnecessary marks get into your dashboard is displaying axis while at the same time having the charts labeled.

In such cases, the axis does not add value to your story because users can see the metrics themselves.

Minimizing much of these unnecessary marks will make your work neat and easy to read.

4. Be conservative with color.

Color is good in our dashboard. It helps us have better memories; color can sway thinking, change action and cause reaction. However, use of color should be limited in dashboards; it’s advisable to use three to four colors in your dashboard (dashboard background included). In case you need to add more colors to your dashboard, you can play around with different gradients of the main color.

5. Add images and icons to enrich your story.

At the heart of every developer, is the goal to tell the story right. While this may not be obvious to do, adding some images and icons related with the context of your story could sometimes help you enrich your story. A good example is this dashboard, where the author used icon of bird, mammal, reptile and plane tell the story.

6. Avoid too much information.

Have you ever found yourself with a well-designed information dashboard, only to realize you can’t use it to answer business questions? If you have, you know how disappointing this is, both as a decision maker or a developer for spending much invaluable time. To avoid these scenarios, it's good to stick to what your projects objective entails. Avoid adding too much information and charts in your dashboard which could distract users from the main objective. It’s good to note that any additional details consumes your resources (performance of your dashboard).

7. Help users interact with your content.

Have you ever visited a new suburb only to find yourself stuck not knowing how to navigate in the area, especially when you don’t have clear guideline? Could be a conference you attended, visiting clients or friends! Can you remember the experience? Probably you do. This is the same experience your users go through when they visit your well designed content only to find themselves stuck without information on how to interact with your content. As a developer, it’s good to help your users by giving them guideline on how to consume your content.

It’s always good to ensure that your title resonates with your story. Also use of color legends should be looked at careful, especially in instances where different charts within the dashboard use different color legends. As a developer, it is important to evaluate the value of your color legend to the user, color legends which don’t necessary guide users interacting with the dashboard are not helpful and should be omitted. Using title color legend could help save space of your dashboard.
