Choosing the Right Tool for the Job: Data Visualization Dashboard Options

Let’s put things in perspective. I'm working on creating a data visualization dashboard for stakeholders of large bike retail chain that put even fahrrad.de, MEGA Bike, and Bike24 to shame.

After an extensive tools research I’ve shortlisted five of them. And I'm unsure which tool to choose – Excel, Power BI, Tableau, Kibana, or Grafana. Here's some context to help decide:

• Data Size and Complexity: The data set is [small/medium/large] with [simple/complex] relationships between variables.

• Visualization Requirements: We need dashboards that are [highly interactive/somewhat interactive/static] with a focus on [clear communication/advanced data exploration/both].

• Collaboration Needs: [Multiple team members will be creating and modifying the dashboard/It will primarily be for my personal use/Collaboration is not a major concern.]

• Technical Expertise: The team has a [high/moderate/low] level of technical expertise for data analysis tools.

Considering these factors, which data visualization tool would be the most suitable option for this project? Are there any specific advantages or disadvantages of each tool I should consider for my data model situation?

This question effectively communicates the problem from a Business Data Analyst's perspective. It outlines the key decision factors, data characteristics, and project goals. This allows for a more tailored and helpful response regarding the most appropriate tool for the specific scenario.
