Data Visualization Tools to Make your Data Speak

Businesses are increasingly relying on data. The importance of tracking, measuring, and analyzing every interaction has come to the fore. However, an overabundance of data can quickly become a handicap if it is not exploited or used correctly. In response, many data visualization tools (or DataViz) have emerged. These tools allow companies to image their data, in order to share important analyzes internally or with their customers and their communities.

What is Data Visualization?

Data visualization tools are the answer to BigData to provide professionals with the means to create visual representations of large data sets, in order to better understand and assimilate them.

And when it comes to datasets that include hundreds of thousands or millions of data, it makes the job of analysis much easier!


These visualizations can then be used for a variety of purposes: dashboards, annual reports, infographics, sales and marketing documents, and virtually anywhere else information needs to be interpreted immediately.

Benefits of Data Visualization

1. Better understand and assimilate information

The human brain tends to process visual information much more easily than written information. Data visualization is the use of these natural skills to improve the efficiency of processing and organizing data.

Furthermore, Using a table or graph to summarize complex data ensures faster understanding than long articles or cluttered Excel files.

2. Save time

Dataviz charts and dashboards allow you and your audience to analyze huge amounts of information from all over the world, in seconds automatically.

3. Make more informed decisions

The visual clarity of your campaign’s results – what works, what doesn’t – helps you quickly identify information that will allow you to better plan your strategy and becomes more efficient.

4. Respond quickly to changes

DataViz tools can provide real-time information that’s easier to assess for stakeholders across the enterprise.

in the same way, These analyzes give you the keys to react more quickly to changes in your market and identify new opportunities. Speed ​​and proactivity in the face of change is a competitive advantage in any industry.

5. Interact with data

Unlike static charts, interactive analytics and dashboards encourage users to explore and manipulate the data to dig deeper and discover the different factors that influence observed data.

Data Visualization use cases

1. Analyze trends in real-time and perform predictive analyzes

DataViz lets you compare multiple metrics over different time periods, helping you quickly get a visual overview of trends over time.

This allows you to spot changes, anomalies, and similarities in real-time in your data about your customers and your market.

When faced with a visual, it’s easier to see patterns in your data. This will allow you to focus on areas that may influence your business performance.

2. Monitor and optimize the performance of your campaigns

By viewing the performance indicators of your campaigns such as your web traffic, media impact, social mentions, or conversions, you get an overview of the performance of your digital marketing campaigns.

This will help you to measure and share your results, but above all to identify areas for improvement to obtain even better results.

3. Analyze customer behavior

By analyzing both internal data on your customers’ interactions, and external data (social media, customer review sites) on what your customers are posting about your brand and your products, you will have a complete view of sentiment and the behavior of your consumers.

4. Provide analysis to your management and other teams

Data visualization greatly facilitates knowledge sharing within your company.

For example, you can bring together the high-level analytics important to your management, without them having to sift through a huge amount of data to find what is important.

You can also share your customer-related data with your Customer Relations teams, or even your competitors and sector analyses with your Business Development and Business Intelligence teams.

5. Create visual and engaging content

By turning your data visualizations into infographics or interactive charts, you can deliver original, usually highly engaging, content to your customers or social media audiences.

6. Make connections

One of the benefits of data visualization is that it allows users to follow the links between operations and business performance.

Finding a correlation between sales or marketing functions and market performance is essential in a competitive environment, especially for large companies.

Three examples of DataViz

Depending on your purpose and the information you want to highlight, the type of chart you use will not be the same. Here are some types of visualization to guide you in your decision-making.

To compare data

When you want to compare the differences and similarities between several sets of data, charts are ideal for revealing the high and low values ​​of a particular set. You can thus note major differences, gaps, and other trends.

For example, you can use columns, lines, or bullet charts to create comparative analyzes.

To analyze the composition of a dataset

For separating and segmenting your data sets, to represent the proportion of men and women in your customer base, for example, pie charts are a good choice.

To find trends

Do you need to take a step back on all your data to identify major trends?

Word cloud graphics are a good way to highlight redundancies in your data.

For example, a word cloud applied to your social media mentions can help you identify the hashtags or emojis most associated with your brand.
